* numeric.c (num_step): use DBL_EPSILON.
* array.c (rb_check_array_type): new function: return an array (convert if possible), or nil. * string.c (rb_check_string_type): new function: return a string (convert if possible), or nil. * numeric.c (rb_dbl_cmp): returns nil if values are not comparable. * numeric.c (fix_cmp,flo_cmp): use rb_num_coerce_cmp() * bignum.c (rb_big_cmp): ditto. * numeric.c (rb_num_coerce_cmp): new coercing function for "<=>", which does not raise TypeError. * numeric.c (do_coerce): can be supress exception now. * object.c (rb_mod_cmp): should return nil for non class/module objects. * re.c (rb_reg_eqq): return false if the argument is not a string. now returns boolean value. * class.c (rb_include_module): argument should be T_MODULE, not T_class, nor T_ICLASS. * eval.c (is_defined): "defined?" should return "assignment" for attribute assignment (e.g. a.foo=b) and indexed assignment (e.g. a[2] = 44). * parse.y (aryset): use NODE_ATTRASGN. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@3169 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
