* object.c (rb_cstr_to_dbl_raise): do not ignore exponent part when the input string longer than internal buffer contains underscore(s). [ruby-core:86836] [Bug #14731] git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@63322 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2018-03-15Add `exception:` keyword in Kernel#Float()mrkn
