- *  call-seq:
- *     format(format_string [, arguments...] )   -> string
- *     sprintf(format_string [, arguments...] )  -> string
- *
- *  Returns the string resulting from applying <i>format_string</i> to
- *  any additional arguments.  Within the format string, any characters
- *  other than format sequences are copied to the result.
- *
- *  The syntax of a format sequence is as follows.
- *
- *    %[flags][width][.precision]type
- *
- *  A format
- *  sequence consists of a percent sign, followed by optional flags,
- *  width, and precision indicators, then terminated with a field type
- *  character.  The field type controls how the corresponding
- *  <code>sprintf</code> argument is to be interpreted, while the flags
- *  modify that interpretation.
- *
- *  The field type characters are:
- *
- *      Field |  Integer Format
- *      ------+--------------------------------------------------------------
- *        b   | Convert argument as a binary number.
- *            | Negative numbers will be displayed as a two's complement
- *            | prefixed with `..1'.
- *        B   | Equivalent to `b', but uses an uppercase 0B for prefix
- *            | in the alternative format by #.
- *        d   | Convert argument as a decimal number.
- *        i   | Identical to `d'.
- *        o   | Convert argument as an octal number.
- *            | Negative numbers will be displayed as a two's complement
- *            | prefixed with `..7'.
- *        u   | Identical to `d'.
- *        x   | Convert argument as a hexadecimal number.
- *            | Negative numbers will be displayed as a two's complement
- *            | prefixed with `..f' (representing an infinite string of
- *            | leading 'ff's).
- *        X   | Equivalent to `x', but uses uppercase letters.
- *
- *      Field |  Float Format
- *      ------+--------------------------------------------------------------
- *        e   | Convert floating point argument into exponential notation
- *            | with one digit before the decimal point as [-]d.dddddde[+-]dd.
- *            | The precision specifies the number of digits after the decimal
- *            | point (defaulting to six).
- *        E   | Equivalent to `e', but uses an uppercase E to indicate
- *            | the exponent.
- *        f   | Convert floating point argument as [-]ddd.dddddd,
- *            | where the precision specifies the number of digits after
- *            | the decimal point.
- *        g   | Convert a floating point number using exponential form
- *            | if the exponent is less than -4 or greater than or
- *            | equal to the precision, or in dd.dddd form otherwise.
- *            | The precision specifies the number of significant digits.
- *        G   | Equivalent to `g', but use an uppercase `E' in exponent form.
- *        a   | Convert floating point argument as [-]0xh.hhhhp[+-]dd,
- *            | which is consisted from optional sign, "0x", fraction part
- *            | as hexadecimal, "p", and exponential part as decimal.
- *        A   | Equivalent to `a', but use uppercase `X' and `P'.
- *
- *      Field |  Other Format
- *      ------+--------------------------------------------------------------
- *        c   | Argument is the numeric code for a single character or
- *            | a single character string itself.
- *        p   | The valuing of argument.inspect.
- *        s   | Argument is a string to be substituted.  If the format
- *            | sequence contains a precision, at most that many characters
- *            | will be copied.
- *        %   | A percent sign itself will be displayed.  No argument taken.
- *
- *  The flags modifies the behavior of the formats.
- *  The flag characters are:
- *

- *   sprintf("%+o", -123) #=> "-173"
- *   sprintf("%o", -123)  #=> "..7605"
- *   sprintf("%#o", -123) #=> "..7605"
- *
- *   # `#' flag for `x' add a prefix `0x' for non-zero numbers.

- *
- *  The field width is an optional integer, followed optionally by a
- *  period and a precision.  The width specifies the minimum number of
- *  characters that will be written to the result for this field.
- *
- *  Examples of width:
- *
- *   # padding is done by spaces,       width=20
- *   # 0 or radix-1.             <------------------>
- *   sprintf("%20d", 123)   #=> "                 123"

- *   sprintf("%-+20d", 123) #=> "+123                "
- *   sprintf("%- 20d", 123) #=> " 123                "
- *   sprintf("%020x", -123) #=> "..ffffffffffffffff85"
- *
- *  For
- *  numeric fields, the precision controls the number of decimal places
- *  displayed.  For string fields, the precision determines the maximum
- *  number of characters to be copied from the string.  (Thus, the format
- *  sequence <code>%10.10s</code> will always contribute exactly ten
- *  characters to the result.)
- *
- *  Examples of precisions:
- *
- *   # precision for `d', 'o', 'x' and 'b' is
- *   # minimum number of digits               <------>
- *   sprintf("%20.8d", 123)  #=> "            00000123"
- *   sprintf("%20.8o", 123)  #=> "            00000173"
- *   sprintf("%20.8x", 123)  #=> "            0000007b"
- *   sprintf("%20.8b", 123)  #=> "            01111011"
- *   sprintf("%20.8d", -123) #=> "           -00000123"
- *   sprintf("%20.8o", -123) #=> "            ..777605"
- *   sprintf("%20.8x", -123) #=> "            ..ffff85"
- *   sprintf("%20.8b", -11)  #=> "            ..110101"
- *
- *   # "0x" and "0b" for `#x' and `#b' is not counted for
- *   # precision but "0" for `#o' is counted.  <------>
- *   sprintf("%#20.8d", 123)  #=> "            00000123"
- *   sprintf("%#20.8o", 123)  #=> "            00000173"
- *   sprintf("%#20.8x", 123)  #=> "          0x0000007b"

- *   sprintf("%#20.8d", -123) #=> "           -00000123"
- *   sprintf("%#20.8o", -123) #=> "            ..777605"
- *   sprintf("%#20.8x", -123) #=> "          0x..ffff85"
- *   sprintf("%#20.8b", -11)  #=> "          0b..110101"
- *
- *   # precision for `e' is number of
- *   # digits after the decimal point           <------>
- *   sprintf("%20.8e", 1234.56789) #=> "      1.23456789e+03"
- *
- *   # precision for `f' is number of
- *   # digits after the decimal point               <------>
- *   sprintf("%20.8f", 1234.56789) #=> "       1234.56789000"
- *
- *   # precision for `g' is number of
- *   # significant digits                          <------->
- *   sprintf("%20.8g", 1234.56789) #=> "           1234.5679"
- *
- *   #                                         <------->
- *   sprintf("%20.8g", 123456789)  #=> "       1.2345679e+08"
- *
- *   # precision for `s' is
- *   # maximum number of characters                    <------>
- *   sprintf("%20.8s", "string test") #=> "            string t"
- *
- *  Examples:
- *
- *     sprintf("%d %04x", 123, 123)               #=> "123 007b"
- *     sprintf("%08b '%4s'", 123, 123)            #=> "01111011 ' 123'"
- *     sprintf("%1$*2$s %2$d %1$s", "hello", 8)   #=> "   hello 8 hello"
- *     sprintf("%1$*2$s %2$d", "hello", -8)       #=> "hello    -8"
- *     sprintf("%+g:% g:%-g", 1.23, 1.23, 1.23)   #=> "+1.23: 1.23:1.23"
- *     sprintf("%u", -123)                        #=> "-123"
- *
- *  For more complex formatting, Ruby supports a reference by name.
- *  %<name>s style uses format style, but %{name} style doesn't.
- *
- *  Examples:
- *    sprintf("%<foo>d : %<bar>f", { :foo => 1, :bar => 2 })
- *      #=> 1 : 2.000000
- *    sprintf("%{foo}f", { :foo => 1 })
- *      # => "1f"
