2022-04-12Fix dtoa buffer overrunNobuyoshi Nakada

2021-05-29Attempt to fix floating point test failureJeremy Evans
The previous behavior depending on exact float values, it seemed to work OK on amd64 and i386, but other CI platforms are experiencing non-deterministic test failures with it. Relax test slightly to hopefully pass on such platforms.
2021-05-29Fix Enumerator::ArithmeticSequence handling of float rangesJeremy Evans
Depending on the float range, there could be an off-by-one error, where the last result that should be in the range was missed. Fix this by checking if the computed value for the expected value outside the range is still inside the range, and if so, increment the step size. Fixes [Bug #16612] Notes: Merged: https://github.com/ruby/ruby/pull/4434
2020-05-12numeric.c: optimize `float ** 2` case by fastpathYusuke Endoh
It would be a relatively frequent case. It is still slower than `float * float` because `*` has a dedicated VM instruction (opt_mult), though.

2018-03-15Add `exception:` keyword in Kernel#Float()mrkn
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
