+Fri Dec 21 15:12:41 2001  Yukihiro Matsumoto  <matz@ruby-lang.org>
 
-	  * improved document/literal service support.
-	    style(rpc,document)/use(encoding, literal) combination are all
-	    supported.  for the detail about combination, see

+	* time.c (time_plus): result should not be negative unless
+	  NEGATIVE_TIME_T is defined.
 
-	  * let WSDLEncodedRegistry#soap2obj map SOAP/OM to Ruby according to
-	    WSDL as well as obj2soap.  closes #70.
+	* time.c (time_new_internal): should check tv_sec overflow too.
 
-	  * let SOAP::Mapping::Object handle XML attribute for doc/lit service.
-	    you can set/get XML attribute via accessor methods which as a name
-	    'xmlattr_' prefixed (<foo name="bar"/> -> Foo#xmlattr_name).
+	* time.c (time_timeval): should check time_t range when time is
+	  initialized from float.
 
-	  === client side ===
+	* time.c (time_plus): uses modf(3).
 
-	  * WSDLDriver capitalized name operation bug fixed.  from
-	    1.5.3-ruby1.8.2, operation which has capitalized name (such as
-	    KeywordSearchRequest in AWS) is defined as a method having
-	    uncapitalized name. (converted with GenSupport.safemethodname
-	    to handle operation name 'foo-bar').  it introduced serious

-	  * added mod_ruby support to SOAP::CGIStub.  rename a CGI script
-	    server.cgi to server.rb and let mod_ruby's RubyHandler handles the
-	    script.  CGIStub detects if it's running under mod_ruby environment
-	    or not.
+	* lib/mkmf.rb: prefix target directories with $(DESTDIR) all.
 
-	  * added fcgi support to SOAP::CGIStub.  see the sample at
-	    sample/soap/calc/server.fcgi.  (almost same as server.cgi but has
-	    fcgi handler at the bottom.)
+	* lib/mkmf.rb: no need to mkdir $(libdir)
 
-	  * allow to return a SOAPFault object to respond customized SOAP fault.
+Thu Dec 20 14:08:20 2001  Minero Aoki  <aamine@loveruby.net>

+	* string.c (str_replace): zero fill for expansion gap.
 
-Thu Oct  9 12:05:46 2003  Eric Sunshine  <sunshine@sunshineco.com>
+	* regex.c (mbctab_euc): set flags on for 0xA1-0xFE.  suggested by
+	  <inaba@st.rim.or.jp>.
 
-	* configure.in: revived NextStep, OpenStep, and Rhapsody ports which
-	  had become unbuildable; enhanced --enable-fat-binary option so that
-	  it accepts a list of desired architectures (rather than assuming a
-	  fixed list), or defaults to a platform-appropriate list if user does
-	  not provide an explicit list; made the default list of architectures
-	  for MAB (fat binary) more comprehensive; now uses -fno-common even
-	  when building the interpreter (in addition to using it for
-	  extensions), thus allowing the interpreter to be embedded into a
-	  plugin module of an external project (in addition to allowing
-	  embedding directly into an application); added checks for
-	  <netinet/in_systm.h> (needed by `socket' extension) and getcwd(); now
-	  ensures that -I/usr/local/include is employed when extensions'
-	  extconf.rb scripts invoke have_header() since extension checks on
-	  NextStep and OpenStep will fail without it if the desired resource
-	  resides in the /usr/local tree; fixed formatting of --help message.
+	* string.c (str_inspect): consider current_mbctype.
 
-	* Makefile.in: $(LIBRUBY_A) rule now deletes the archive before
-	  invoking $(AR) since `ar' on Apple/NeXT can not "update" MAB archives
-	  (see configure's --enable-fat-binary option); added rule for new
-	  missing/getcwd.c.
+Sun Jul 26 15:37:11 1998  Tadayoshi Funaba  <tadf@kt.rim.or.jp>
 
-	* defines.h: fixed endian handling during MAB build (see configure's
-	  --enable-fat-binary option) to ensure that all portions of the
-	  project see the correct WORDS_BIGENDIAN value (some extension modules
-	  were getting the wrong endian setting); added missing constants
-	  GETPGRP_VOID, WNOHANG, WUNTRACED, X_OK, and type pid_t for NextStep
-	  and OpenStep; removed unnecessary and problematic HAVE_SYS_WAIT_H
-	  define in NeXT section.
+	* array.c (ary_s_new): Array.new(1<<30) dumps core.
 
-	* dir.c: do not allow NAMLEN() macro to trust dirent::d_namlen on
-	  NextStep since, on some installations, this value always resolves
-	  uselessly to zero.
+Fri Jul 24 13:40:19 1998  Yukihiro Matsumoto  <matz@netlab.co.jp>
 
-	* dln.c: added error reporting to NextStep extension loader since the
-	  previous behavior of failing silently was not useful; now ensures
-	  that NSLINKMODULE_OPTION_BINDNOW compatibility constant is defined
-	  for OpenStep and Rhapsody; no longer includes <mach-o/dyld.h> twice
-	  on Rhapsody since this header lacks multiple-include protection,
-	  which resulted in "redefinition" compilation errors.
+	* version 1.1c1 released.
 
-	* main.c: also create hard reference to objc_msgSend() on NeXT
-	  platforms (in addition to Apple platforms).
+Fri Jul 24 02:10:22 1998  Yukihiro Matsumoto  <matz@netlab.co.jp>
 
-	* lib/mkmf.rb: now exports XCFLAGS from configure script to extension
-	  makefiles so that extensions can be built MAB (see configure's
-	  --enable-fat-binary option); also utilize XCFLAGS in cc_command()
-	  (but not cpp_command() because MAB flags are incompatible with
-	  direct invocation of `cpp').
+	* marshal.c (r_bytes2): allocated buffer size was too short.
 
-	* ext/curses/extconf.rb: now additionally checks for presence of these
-	  curses functions which are not present on NextStep or Openstep:
-	  bkgd(), bkgdset(), color(), curs(), getbkgd(), init(), scrl(), set(),
-	  setscrreg(), wattroff(), wattron(), wattrset(), wbkgd(), wbkgdset(),
-	  wscrl(), wsetscrreg()
+	* marshal.c (w_object): saves all options, not only casefold flag.
 
-	* ext/curses/curses.c: added appropriate #ifdef's for additional set of
-	  curses functions now checked by extconf.rb; fixed curses_bkgd() and
-	  window_bkgd() to correctly return boolean result rather than numeric
-	  result; fixed window_getbkgd() to correctly signal an error by
-	  returning nil rather than -1.
+	* re.c (reg_clone): now copies options properly.
 
-	* ext/etc/etc.c: setup_passwd() and setup_group() now check for null
-	  pointers before invoking rb_tainted_str_new2() upon fields extracted
-	  from `struct passwd' and `struct group' since null pointers in some
-	  fields are common on NextStep/OpenStep (especially so for the
-	  `pw_comment' field) and rb_tainted_str_new2() throws an exception
-	  when it receives a null pointer.
+	* re.c (reg_get_kcode): code number was wrong.
 
-	* ext/pty/pty.c: include "util.h" for strdup()/ruby_strdup() for
-	  platforms such as NextStep and OpenStep which lack strdup().
+Thu Jul 23 13:11:32 1998  Yukihiro Matsumoto  <matz@netlab.co.jp>
 
-	* ext/socket/getaddrinfo.c: cast first argument of getservbyname(),
-	  gethostbyaddr(), and gethostbyname() from (const char*) to non-const
-	  (char*) for older platforms such as NextStep and OpenStep.
+	* eval.c (rb_attr): argument should be symbol or string.
 
-	* ext/socket/socket.c: include "util.h" for strdup()/ruby_strdup() for
-	  platforms such as NextStep and OpenStep which lack strdup(); include
-	  <netinet/in_systm.h> if present for NextStep and OpenStep; cast first
-	  argument of gethostbyaddr() and getservbyname() from (const char*) to
-	  non-const (char*) for older platforms.

-## Transitional Hack ####
-#
-#  RDoc was initially distributed independently, and installed
-#  itself into <prefix>/lib/ruby/site_ruby/<ver>/rdoc...
-#
-#  Now that RDoc is part of the distribution, it's installed into
-#  <prefix>/lib/ruby/<ver>, which unfortunately appears later in the
-#  search path. This means that if you have previously installed RDoc,
-#  and then install from ruby-lang, you'll pick up the old one by
-#  default. This hack checks for the condition, and readjusts the
-#  search path if necessary.
-

-  It seems as if you have a previously-installed RDoc in

-# == Installing Documentation
-#
-# 'ri' uses a database of documentation built by the RDoc utility.
-# 
-# So, how do you install this documentation on your system?
-# It depends on how you installed Ruby.
-#
-# <em>If you installed Ruby from source files</em> (that is, if it some point
-# you typed 'make' during the process :), you can install the RDoc
-# documentation yourself. Just go back to the place where you have 
-# your Ruby source and type
-#
-#    make install-doc
-#
-# You'll probably need to do this as a superuser, as the documentation
-# is installed in the Ruby target tree (normally somewhere under 
-# <tt>/usr/local</tt>.
-#
-# <em>If you installed Ruby from a binary distribution</em> (perhaps
-# using a one-click installer, or using some other packaging system),
-# then the team that produced the package probably forgot to package
-# the documentation as well. Contact them, and see if they can add
-# it to the next release.

-= command line options
+This file is not actively maintained.  See ChangeLog for recent changes.
 
-: -W option
+: open-uri.rb
 
-  new option to specify warning level. -W0 to shut up warnings, -W1 for normal level,
-  -W2 for verbose level.  -w equals to -W2.
+  Imported.  This is an easy-to-use wrapper for net/http and net/ftp.
 
-= language syntax
-
-: arbitrary delimited string array
-
-  %W(...) notation, word list literal like %w(...) with the
-  exception that #{} interpolation is allowed.
-
-: arbitrary delimited symbol literl
-
-  :"foo", :"foo#{bar}", etc.
-
-: expression interpolation in strings
-
-  Now arbitrary statements are allowed inside #{} interpolation
-  without escapes.  In other hand, they can no longer access to
-  variables defined in eval.
-
-: negative number literals
-
-  Digits preceded minus sign is a literal integer.
-
-: array expansion
-
-  Fixed with the following behavior:
-
-    a = *[1]
-    p a #=> [1]
-
-  Now 1-element array in rhs is expanded properly.
-
-    a = *[1]
-    p a #=> 1
-
-: break and next
-
-  Extended to take an optional expression, which is used as a value
-  for termination.
-
-: direct assignment to Foo::Bar is allowed
-
-  also, you can define "class Foo::Bar; end".
-
-= language core
-
-: $stdin, $stdout, $stderr
+: Class#inherited
 
-  can be assignable again.  the original stdio are preserved as STDIN,
-  STDOUT, STDERR.
+  Method is called when Class is inherited by another class.
 
-: $VERBOSE now has 3 levels
+	class A; end
+	def A.inherited(by)
+          puts "A inherited by #{by.inspect}"
+        end
+        class B < A; end
 
-  nil - silence, false - medium (default), true - verbose
+        Prints out "A inherited by B"
 
-: allocation framework
+: String#to_i
 
-  any instance of class can be allocated by class.allocate,
-  (except for a few classes).
+  Now accepts optional base argument.
 
-: comparison of exception classes in a rescue clause
+	"101".to_i(10) => 101
+	"101".to_i(2)  => 5
+	"101".to_i(8)  => 65
+	"101".to_i(16) => 257
 
-  changed to use Module#=== for comparing $! with the exception
-  class specified in each rescue clause.
+  A base argument of 0 guesses at the base.
 
-  as the previous behavior was to use kind_of?, the effect is limited
-  to the SystemCallError case.  SystemCallError.=== has been newly
-  defined to return true when the two have the same errno.  With this
-  change, SystemCallError's with the same errno, such as Errno::EAGAIN
-  and Errno::EWOULDBLOCK, can both be rescued by listing just one of
-  them.
+	"101".to_i(0)   => 101

+	"0101".to_i(0)  => 65

-: constants lookup
+: Set class (set.rb)
 
-  improved at the performance of searching by using an internal hash
-  table.
+  Imported.
 
-  calls const_missing method of the class/module, if constant is not
-  found in the look up path.
+: OptionParser module
 
-: expression parenthesis in the first argument
+  Imported.  Command line options utility library.
 
-  altered to get the following code (note the space after p):
+: parser
 
-    p ("xx"*2).to_i
+  %W(...) notation, word list literal like %w(...) with the
+  exception that #{} interpolation is allowed.
 
-  Interpreted as:
+: parser
 
-    p (("xx"*2).to_i)
+  Now arbitrary statements are allowed inside #{} interpolation
+  without escapes.  In other hand, they can no longer access to
+  variables defined in eval.
 
-  Instead of:
+: parser
 
-    (p("xx"*2)).to_i
+  Digits preceded minus sign is a literal integer.
 
-: implicit comparison in conditional expressions
+: IO::sysopen
 
-  Obsoleted except when it is used in -e.
+  New method to get a raw file descriptor.
 
-  : between Range and $.
-      Use explicit comparison instead.
+: TCPServer#accept, UNIXServer#accept, Socket#accept
 
-  : between Regexp and $_
-      Use the unary method ~/re/ instead.
+  New methods to return an accepted socket fd.
 
-: to_str
+: Date and DateTime
 
-  added to get objects which define to_str() treated as String's.
+  lib/date.rb now provides both Date and DateTime.
 
-  now almost all the built-in methods try each argument with to_str()
-  when they expect it to be a String.
+  Some methods have been renamed.  But the old names are still alive.
 
-    foo = Object.new
-    class <<foo
-      def to_str
-        "foo"
-      end

-       ruby 1.7.0 (2001-05-02) [i586-linux]
+  Some new methods have been added (Date::parse, Date#strftime, etc.).
 
-: multiple assignment behavior
+  Date#mjd now returns the chronological modified Julian day number.
 
-  Fixed so that "*a = nil" results in "a == []".
+  All facilities about tjd have been removed.
 
-= changes in core class library
+: Thread#join
 
-: open
+  Optional argument limits maximum time to wait the thread in second.
+  And returns nil if timed out.
 
-  Extended so that when the third argument is permission flags it
-  calls open(2) instead of fopen(3).
+: Array#filter
 
-: sprintf
+  Previously deprecated, now removed.  Use Array#collect!.
 
-  new format specifier "%p" is available.
+: dl module
 
-: lambda and proc
+  Imported. An interface to the dynamic linker.
 
-  Proc object returns from these methods has the following attributes:
+: IO#sysseek
 
-  * strict argument number check
-  * break and return terminates the proc execution.
+  Added.
 
-: warn(message)
+: IO

-  using "allocate", then calls its "marshal_load" with dumped data.
-  Marshal format version is now 4.8 (was 4.6 in 1.6.8).
+  Added for convenience of Regexp#match. [ruby-dev:12766]

+  Previously we had to do:
 
-  Fixed not to dump anonymous classes/modules.
+    foo, bar, baz = /(\w+?)\s+(\w+?)\s+(\w+)/.match("foo bar baz").to_a[1..-1]
+    p [foo, bar, baz]
 
-  Fixed with loading modules.

- *     
- *  However, consider the case where comparing the keys is a non-trivial
- *  operation. The following code sorts some files on modification time
- *  using the basic <code>sort</code> method.
- *     
- *     files = Dir["*"]
- *     sorted = files.sort {|a,b| File.new(a).mtime <=> File.new(b).mtime}
- *     sorted   #=> ["mon", "tues", "wed", "thurs"]
- *     
- *  This sort is inefficient: it generates two new <code>File</code>
- *  objects during every comparison. A slightly better technique is to
- *  use the <code>Kernel#test</code> method to generate the modification
- *  times directly.
- *     
- *     files = Dir["*"]
- *     sorted = files.sort { |a,b|
- *       test(?M, a) <=> test(?M, b)

- *     sorted   #=> ["mon", "tues", "wed", "thurs"]
- *     
- *  This still generates many unnecessary <code>Time</code> objects. A
- *  more efficient technique is to cache the sort keys (modification
- *  times in this case) before the sort. Perl users often call this
- *  approach a Schwartzian Transform, after Randal Schwartz. We
- *  construct a temporary array, where each element is an array
- *  containing our sort key along with the filename. We sort this array,
- *  and then extract the filename from the result.
- *     
- *     sorted = Dir["*"].collect { |f|
- *        [test(?M, f), f]
- *     }.sort.collect { |f| f[1] }
- *     sorted   #=> ["mon", "tues", "wed", "thurs"]
- *     
- *  This is exactly what <code>sort_by</code> does internally.

- *  <code>Errno::EACCES</code>, <code>Errno::EAGAIN</code>,
- *  <code>Errno::EINTR</code>, and so on.
- *     
- *  The integer operating system error number corresponding to a

- * PRE_GETCONTEXT and POST_GETCONTEXT is a magic for getcontext, gcc,

- *
- * Assume following code sequence.
- * 
- * 1. set a register in the register stack/window such as r32/l0.
- * 2. call getcontext.
- * 3. use the register.
- * 4. update the register for other use.
- * 5. call setcontext indirectly (or directly).
- *
- * This code should be run as 1->2->3->4->5->3->4.
- * But after second getcontext return (second 3),
- * the register is broken (updated).
- * It's because getcontext/setcontext doesn't preserve the content of the
- * register stack/window.
- *
- * setjmp also doesn't preserve the content of the register stack/window.
- * But it has not the problem because gcc knows setjmp may return twice.
- * gcc detects setjmp and generates setjmp safe code.
- *
- * So setjmp calls before and after the getcontext call makes the code
- * somewhat safe.
- * It fix the problem on IA64.
- * It is not required that setjmp is called at run time, since the problem is
- * register usage.

- * Document-class: UnboundMethod
- *
- *  Ruby supports two forms of objectified methods. Class
- *  <code>Method</code> is used to represent methods that are associated
- *  with a particular object: these method objects are bound to that
- *  object. Bound method objects for an object can be created using
- *  <code>Object#method</code>.
- *     
- *  Ruby also supports unbound methods; methods objects that are not
- *  associated with a particular object. These can be created either by
- *  calling <code>Module#instance_method</code> or by calling
- *  <code>unbind</code> on a bound method object. The result of both of
- *  these is an <code>UnboundMethod</code> object.
- *     
- *  Unbound methods can only be called after they are bound to an
- *  object. That object must be be a kind_of? the method's original
- *  class.
- *     
- *     class Square
- *       def area
- *         @side * @side
- *       end
- *       def initialize(side)
- *         @side = side
- *       end
- *     end
- *     
- *     area_un = Square.instance_method(:area)
- *     
- *     s = Square.new(12)
- *     area = area_un.bind(s)
- *     area.call   #=> 144
- *     
- *  Unbound methods are a reference to the method at the time it was
- *  objectified: subsequent changes to the underlying class will not
- *  affect the unbound method.
- *     
- *     class Test
- *       def test
- *         :original
- *       end

- * Copyright (C) 2002 by Shigeo Kobayashi <shigeo@tinyforest.gr.jp>.
- * You may distribute under the terms of either the GNU General Public
- * License or the Artistic License, as specified in the README file
- * of the BigDecimal distribution.
- *
- * Documented by mathew <meta@pobox.com>.
- *
- * = Introduction
- *
- * Ruby provides built-in support for arbitrary precision integer arithmetic.
- * For example:
- *
- * 42**13   ->   1265437718438866624512
- *
- * BigDecimal provides similar support for very large or very accurate floating
- * point numbers.
- *
- * Decimal arithmetic is also useful for general calculation, because it
- * provides the correct answers people expect--whereas normal binary floating
- * point arithmetic often introduces subtle errors because of the conversion
- * between base 10 and base 2. For example, try:
- *
- *   sum = 0
- *   for i in (1..10000)
- *     sum = sum + 0.0001
- *   end
- *   print sum
- *
- * and contrast with the output from:
- *
- *   require 'bigdecimal'
- *
- *   sum = BigDecimal.new("0")
- *   for i in (1..10000)
- *     sum = sum + BigDecimal.new("0.0001")
- *   end
- *   print sum
- *
- * Similarly:
- *
- * (BigDecimal.new("1.2") - BigDecimal("1.0")) == BigDecimal("0.2") -> true
- *
- * (1.2 - 1.0) == 0.2 -> false
- *
- * = Special features of accurate decimal arithmetic
- *
- * Because BigDecimal is more accurate than normal binary floating point
- * arithmetic, it requires some special values.
- *
- * == Infinity
- *
- * BigDecimal sometimes needs to return infinity, for example if you divide
- * a value by zero.
- *
- * BigDecimal.new("1.0") / BigDecimal.new("0.0")  -> infinity
- *
- * BigDecimal.new("-1.0") / BigDecimal.new("0.0")  -> -infinity
- *
- * You can represent infinite numbers to BigDecimal using the strings
- * 'Infinity', '+Infinity' and '-Infinity' (case-sensitive)
- *
- * == Not a Number
- *
- * When a computation results in an undefined value, the special value NaN
- * (for 'not a number') is returned.
- *
- * Example:
- *
- * BigDecimal.new("0.0") / BigDecimal.new("0.0") -> NaN
- *
- * You can also create undefined values.  NaN is never considered to be the
- * same as any other value, even NaN itself:
- *
- * n = BigDecimal.new('NaN')
- *
- * n == 0.0 -> nil
- *
- * n == n -> nil
- *
- * == Positive and negative zero
- *
- * If a computation results in a value which is too small to be represented as
- * a BigDecimal within the currently specified limits of precision, zero must
- * be returned.
- *
- * If the value which is too small to be represented is negative, a BigDecimal
- * value of negative zero is returned. If the value is positive, a value of
- * positive zero is returned.
- *
- * BigDecimal.new("1.0") / BigDecimal.new("-Infinity") -> -0.0
- *
- * BigDecimal.new("1.0") / BigDecimal.new("Infinity") -> 0.0
- *
- * (See BigDecimal.mode for how to specify limits of precision.)
- *
- * Note that -0.0 and 0.0 are considered to be the same for the purposes of
- * comparison.
- *
- * Note also that in mathematics, there is no particular concept of negative 
- * or positive zero; true mathematical zero has no sign.

-<H2>Introduction</H2>
-Ruby already has builtin (variable length integer number) class Bignum. Using Bignum class,you can obtain
- any integer value in magnitude. But, variable length decimal number class is not yet built in. 
-This is why I made variable length floating class BigDecimal.
-Feel free to send any comments or bug reports to me.
-<A HREF="mailto:shigeo@tinyforest.gr.jp">shigeo@tinyforest.gr.jp</A>
-I will try(but can't promise) to fix bugs reported.

-<H2>Installation</H2>
-The Ruby latest version can be downloaded from <A HREF="http://www.ruby-lang.org/en/">Official Ruby page</A>.
-Once decompress the downloaded Ruby archive,follow the normal installation procedures according to the 
-documents included.

-<H2>Usage and methods</H2>
-Suppose you already know Ruby programming,
-to create BigDecimal objects,the program would like:<BR>
-
-<CODE><PRE>
-   require 'bigdecimal'
-   a=BigDecimal::new("0.123456789123456789")
-   b=BigDecimal("123456.78912345678",40)
-   c=a+b
-</PRE></CODE>
-
-<H3>List of methods</H3>
-In 32 bits integer system,every 4 digits(in decimal) are computed simultaneously.
-This means the number of significant digits in BigDecimal is always a multiple of 4.
-<P>
-Some more methods are available in Ruby code (not C code). 
-Functions such as sin,cos ...,are in math.rb in bigdecimal directory.
-To use them,require math.rb as:
-<CODE><PRE>
-require "bigdecimal/math.rb"
-</PRE></CODE>
-For details,see the math.rb code and comments.
-Other utility methods are in util.rb.
-To use util.rb, require it as:
-<CODE><PRE>
-require "bigdecimal/util.rb"
-</PRE></CODE>
-For details,see the util.rb code.

-"new" method creates a new BigDecimal object.<BR>
-a=BigDecimal::new(s[,n]) or<BR>
-a=BigDecimal(s[,n]) or<BR>
-where:<BR>
-s: Initial value string. Spaces will be ignored. Any unrecognizable character for 
-representing initial value terminates the string.<BR>
-n: Maximum number of significant digits of a. n must be a Fixnum object.
-If n is omitted or is equal to 0,then the maximum number of significant digits of a is determined from the length of s.
-Actual number of digits handled in computations are usually gretaer than n.<BR>
-n is useful when performing divisions like
-<CODE><PRE>
-BigDecimal("1")    / BigDecimal("3")    # => 0.3333333333 33E0
-BigDecimal("1",10) / BigDecimal("3",10) # => 0.3333333333 3333333333 33333333E0

-<H3>About 'coerce'</H3>
-<B>For the binary operation like A op B:</B>
-<DL>
-<DT> 1.Both A and B are BigDecimal objects</DT>
-<DD> A op B is normally performed.</DD>
-<DT> 2.A is the BigDecimal object but B is other than BigDecimal object</DT>
-<DD> Operation is performed,after B is translated to correcponding BigDecimal object(because BigDecimal supports coerce method).</DD>
-<DT> 3.A is not the BigDecimal object but B is BigDecimal object</DT>
-<DD>If A has coerce mthod,then B will translate A to corresponding 
-BigDecimal object and the operation is performed,otherwise an error occures.</DD>
-</DL>
-
-String is not translated to BigDecimal in default.
-Uncomment /* #define ENABLE_NUMERIC_STRING */ in bigdecimal.c, compile and install 
-again if you want to enable string to BigDecimal conversion.
-Translation stops without error at the character representing non digit.
-For instance,"10XX" is translated to 10,"XXXX" is translated to 0.<BR>
-String representing zero or infinity such as "Infinity","+Infinity","-Infinity",and "NaN" can also be translated to BigDecimal unless false is specified by mode method.<BR>
-
-BigDecimal class supports coerce method(for the details about coerce method,see Ruby documentations). This means the most binary operation can be performed if the BigDecimal object is at the left hand side of the operation.<BR><BR>
-
- For example:
-<CODE><PRE>
-  a = BigDecimal.E(20)
-  c = a * "0.123456789123456789123456789" # A String is changed to BigDecimal object.
-</PRE></CODE>
-is performed normally.<BR>
- But,because String does not have coerce method,the following example can not be performed.<BR>
-
-<CODE><PRE>
-  a = BigDecimal.E(20)
-  c = "0.123456789123456789123456789" * a # ERROR
-</PRE></CODE>
-
-If you actually have any inconvenience about the error above.
-You can define a new class derived from String class,
-and define coerce method within the new class.<BR>

-<H2>Internal structure</H2>
-BigDecimal number is defined by the structure Real in BigDecimal.h.
-Digits representing a float number are kept in the array frac[] defined in the structure.
-In the program,any floating number(BigDecimal number) is represented as:<BR>
- <BigDecimal number> = 0.xxxxxxxxx*BASE**n<BR><BR>
-where 'x' is any digit representing mantissa(kept in the array frac[]),
-BASE is base value(=10000 in 32 bit integer system),
-and n is the exponent value.<BR>
-Larger BASE value enables smaller size of the array frac[],and increases computation speed.
-The value of BASE is defined ind VpInit(). In 32 bit integer system,this value is 
-10000. In 64 bit integer system,the value becomes larger.
-BigDecimal has not yet been compiled and tested on 64 bit integer system.
-It will be very nice if anyone try to run BigDecimal on 64 bit system and
- inform me the results.
-When BASE is 10000,an element of the array frac[] can have vale of from 0 to 9999.

-<H2>Binary or decimal number representation</H2>
-I adopted decimal number representation for BigDecimal implementation.
-Of cource,binary number representation is common on the most computers.
-
-<H3>Advantages using decimal representation</H3>
-The reason why I adopted decimal number representation for BigDecimal is:<BR>
-<DL>
-<DT>Easy for debugging
-<DD>The floating number 1234.56784321 can be easily represented as:<BR>
-  frac[0]=1234,frac[1]=5678,frac[2]=4321,exponent=1,and sign=2.
-<DT>Exact representation
-<DD>Following program can add all numbers(in decimal) in a file
- without any error(no round operation).<BR>
-
-<CODE><PRE>
-   file = File::open(....,"r")
-   s = BigDecimal::new("0")
-   while line = file.gets
-      s = s + line
-   end
-</PRE></CODE>
-
-If the internal representation is binary,translation from decimal to 
-binary is required and the translation error is inevitable.
-For example, 0.1 can not exactly be represented in binary.<BR>
-0.1 => b1*2**(-1)+b1*2**(-2)+b3*2**(-3)+b4*2**(-4)....<BR>
-where b1=0,b2=0,b3=0,b4=1...<BR>
-bn(n=1,2,3,...) is infinite series of digit with value of 0 or 1,
-and rounding operation is necessary but where we should round the series ?
-Of cource,exact "0.1" is printed if the rouding operation is properly done,
-<DT>Significant digit we can have is automatically determined
-<DD>In binary representation,0.1 can not be represented in finite series of digit.
-
-But we only need one element(frac[0]=1) in decimal representation.
-This means that we can always determine the size of the array frac[] in Real 
-structure.
-</DL>
-
-<H3>Disadvantage of decimal representation</H3>
-Advantages stated so far can also be disadvantages if the input from outside is
- represented in binary.
-Translation error from decimal to binary or vice versa is inevitable.
-So,translation from Float(binary) to BigDecimal(decimal) is not alway done exactly.
-
-<H4>Which is the first input?</H4>
-Because most people uses decimal notatin for numeric data representation,
-BigDecimal can handle numeric data without loss of translation error.

-<H2>Resulting number of significant digits</H2>
-For the fundamental arithmetics such as addition,subtraction,
-multiplication,and division,I prepared 2 group of methods<BR>
-
-<H3>1. +,-,*,/</H3>
-For the operation + - * /,you can not specify the resulting

-Resulting number of significant digits are defined as:<BR>

-maximum significant digits of both side of the operator.<BR>
-1.2 For + and -,resulting number of significant digits is determined so that
- no round operation is needed. <br>
-For example, c has more than 100 siginificant digits if c is computed as:<BR>
-c = 0.1+0.1*10**(-100)<br>
-<BR>
-As +,-,and * are always exact(no round operation is performed unless BigDecimal.limit is specified),
-which means more momories are required to keep computation results.
-But,the division such as c=1.0/3.0 will always be rounded.<BR>
-
-<H3>2. add,sub,mult,div</H3>
-The length of the significant digits obtained from +,-,*,/ 
-is always defined by that of right and left side of the operator.
-To specify the length of the significant digits by your self,
-use methos add,sub,mult,div.

-<H2>はじめに</H2>
-Ruby には Bignum というクラスがあり、数百桁の整数でも計算することができます。
-ただ、任意桁の浮動少数点演算用クラスが無いようです。そこで、
-任意桁の浮動少数点演算用拡張ライブラリ BigDecimal を作成しました。
-不具合や助言・提案がある場合どしどし、
-<A HREF="mailto:shigeo@tinyforest.gr.jp">shigeo@tinyforest.gr.jp</A>
-までお知らせください。不具合を直す気は大いにあります。ただ、時間などの関係で約束
-はできません。また、結果についても保証できるものではありません。
-予め、ご了承ください。

-<H2>インストールについて</H2>
-BigDecimal を含む Ruby の最新版は<A HREF="http://www.ruby-lang.org/ja/">Ruby公式ページ</A>からダウンロードできます。
-ダウンロードした最新版を解凍したら、通常のインストール手順を実行して下さい。
-Ruby が正しくインストールされれば、同時に BigDecimal も利用できるようになるはずです。
-ソースファイルは 
-bigdecimal.c,bigdecimal.h

-「Rubyは既に書ける」という前提で、
-<CODE><PRE>
-require 'bigdecimal'
-a=BigDecimal::new("0.123456789123456789")
-b=BigDecimal("123456.78912345678",40)
-c=a+b
-</PRE></CODE>
-<br>
-というような感じで使用します。
-
-<H3>メソッド一覧</H3>
-以下のメソッドが利用可能です。
-「有効桁数」とは BigDecimal が精度を保証する桁数です。
-ぴったりではありません、若干の余裕を持って計算されます。
-また、例えば３２ビットのシステムでは１０進で４桁毎に計算します。従って、現状では、
-内部の「有効桁数」は４の倍数となっています。
-<P>
-以下のメソッド以外にも、(C ではない) Ruby ソースの形で
-提供されているものもあります。例えば、
-<CODE><PRE>
-require "bigdecimal/math.rb"
-</PRE></CODE>
-とすることで、sin や cos といった関数が使用できるようになります。
-使用方法など、詳細は math.rb の内容を参照して下さい。
-
-その他、Float との相互変換などのメソッドが util.rb でサポートされています。
-利用するには
-<CODE><PRE>
-require "bigdecimal/util.rb"

-無限大や非数を表す文字として、"Infinity"、"+Infinity"、"-Infinity"、"NaN"
-も使用できます(大文字・小文字を区別します)。ただし、mode メソッドで false を
-指定した場合は例外が発生します。
-<BR>
-また、BigDecimalクラスは coerce（Ruby本参照）をサポートしています。
-従って、BigDecimal オブジェクトが右にある場合も大抵は大丈夫です。
-ただ、現在の Ruby インタプリタの仕様上、文字列が左にあると計算できません。<BR>

-<H2>2進と10進</H2>
-BigDecimal は <浮動小数点数> = 0.xxxxxxxxx*10**n という10進形式で数値を保持します。
-しかし、計算機の浮動小数点数の内部表現は、言うまでもなく <浮動小数点数> = 0.bbbbbbbb*2**n という
-2進形式が普通です(x は 0 から 9 まで、b は 0 か 1 の数字)。
-BigDecimal がなぜ10進の内部表現形式を採用したのかを以下に説明します。
-<H4>10進のメリット</H4>
-<DL>
-<DT>デバッグのしやすさ
-<DD>まず、プログラム作成が楽です。frac[0]=1234、frac[1]=5678、frac[2]=4321、
-exponent=1、sign=2 なら数値が 1234.56784321 であるのは見れば直ぐに分かります。
-
-<DT>10進表記された数値なら確実に内部表現に変換できる
-<DD>例えば、以下のようなプログラムは全く誤差無しで
-計算することができます。以下の例は、一行に一つの数値
-が書いてあるファイル file の合計数値を求めるものです。
-<CODE><PRE>
-   file = File::open(....,"r")
-   s = BigDecimal::new("0")
-   while line = file.gets
-      s = s + line
-   end
-</PRE></CODE>
-この例を2進数でやると誤差が入り込む可能性があります。
-例えば 0.1 を2進で表現すると 0.1 = b1*2**(-1)+b1*2**(-2)+b3*2**(-3)+b4*2**(-4)....
-と無限に続いてしまいます(b1=0,b2=0,b3=0,b4=1...)。ここで bn(n=1,2,3,...) は
-2進を表現する 0 か 1 の数字列です。従って、どこかで打ち切る必要があります。
-ここで変換誤差が入ります。もちろん、これを再度10進表記にして印刷するような
-場合は適切な丸め操作（四捨五入）によって再び "0.1" と表示されます。しかし、
-内部では正確な 0.1 ではありません。
-
-<DT>有効桁数は有限である（つまり自動決定できる）
-<DD>0.1 を表現するための領域はたった一つの配列要素（ frac[0]=1 ）で済みます。
-配列要素の数は10進数値から自動的に決定できます。これは、可変長浮動小数点演算では
-大事なことです。逆に 0.1 を2進表現したときには2進の有効桁をいくつにするのか 0.1 を
-見ただけでは決定できません。
-</DL>
-
-<H3>10進のデメリット</H3>
-実は今までのメリットは、そのままデメリットにもなります。
-そもそも、10進を2進、2進を10進に変換するような操作は変換誤差
-を伴う場合を回避することはできません。
-既に計算機内部に取り込まれた2進数値を BigDecimal の内部表現に
-変換するときには誤差が避けられない場合があります。
-
-<H3>最初は何か？</H3>
-自分で計算するときにわざわざ2進数を使う人は極めてまれです。
-計算機にデータを入力するときもほとんどの場合、
-10進数で入力します。その結果、double 等の計算機内部
-表現は最初から誤差が入っている場合があります。
-BigDecimal はユーザ入力を誤差無しで取り込むことができます。
-デバッグがしやすいのと、データ読みこみ時に誤差が入らない
-というのが実際のメリットです。
