Subject: [ruby-core:68325] [Ruby trunk - Feature #10909] [Open] [PATCH 2/2] math.c: Direct casting from Rational to double.

Feature #10909: [PATCH 2/2] math.c: Direct casting from Rational to double.
https://bugs.ruby-lang.org/issues/10909

* Author: gogo tanaka

* Priority: Normal

----------------------------------------
Hi, this proposal is continued from [Feature 10800](https://bugs.ruby-lang.org/issues/10800) and [Feature 10785](https://bugs.ruby-lang.org/issues/10785)
I'd like to do cast from Rational to double unless Rational#to_f is redefined.
Along with that, I've introduced some new macros(`fix2dbl_without_to_f`, `big2dbl_without_to_f`, ..) and added test cases.

Please feel free to let me know if there are something you don't like.

thanks.
