* rational.c (rb_flt_rationalize_with_prec): new public C function
to rationalize a Float instance with a precision. * rational.c (rb_flt_rationalize): new public C function to rationalize a Float instance. A precision is calculated from the given float number. * include/ruby/intern.h: Add rb_flt_rationalize_with_prec and rb_flt_rationalize. * parse.y: implement number literal suffixes, 'r' and 'i'. [ruby-core:55096] [Feature #8430] * bootstraptest/test_literal_suffix.rb: add tests for parser to scan number literals with the above tsuffixes. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@42311 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
