* numeric.c: optimize `float ** 2` case by fastpathYusuke Endoh2020-05-121-0/+1
| | | | | | It would be a relatively frequent case. It is still slower than `float * float` because `*` has a dedicated VM instruction (opt_mult), though.

* Add `exception:` keyword in Kernel#Float()mrkn2018-03-151-0/+38
| | | | | | | | | | Support `exception:` keyword argument in `Kernel#Float()`. If `exception:` is `false`, `Kernel#Float()` returns `nil` if the given value cannot be interpreted as a float value. The default value of `exception:` is `true`. This is part of [Feature #12732]. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@62758 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
