2021-08-18rb_fix2uint should use FIXNUM_NEGATIVE_PJohn Hawthorn
rb_num_negative_int_p is equivalent to calling the "<" method on Integer (and checking whether it is overridden), where in this case we are interested in whether the "actual" value can fit inside an unsigned int. This also was slow because rb_num_negative_int_p calls rb_method_basic_definition_p, doing a method lookup to check for < being overridden. This replaces the check in both rb_fix2uint and rb_fix2ushort with FIXNUM_NEGATIVE_P which simply checks whether the VALUE is signed. Notes: Merged: https://github.com/ruby/ruby/pull/4747
2021-08-06Use Rational for Float#round with ndigits > 14Jeremy Evans
ndigits higher than 14 can result in values that are slightly too large due to floating point limitations. Converting to rational for the calculation and then back to float fixes these issues. Fixes [Bug #14635] Fixes [Bug #17183] Co-authored by: Yusuke Endoh <mame@ruby-lang.org> Notes: Merged: https://github.com/ruby/ruby/pull/4682

2021-07-29Improve performance of Integer#digitsJeremy Evans
This speeds up performance by multiple orders of magnitude for large integers. Fixes [Bug #14391] Co-authored-by: tompng (tomoya ishida) <tomoyapenguin@gmail.com> Notes: Merged: https://github.com/ruby/ruby/pull/4584
2021-07-27Make Float#floor with ndigits argument handle errorJeremy Evans
The previous implementation could result in a returned float that is 1/(10**ndigits) too low. First try adding one before dividing, and if that results in a value that is greater than the initial number, then try the original calculation. Spec added for ciel, but the issue doesn't appear to affect ciel, at least not for the same number. If the issue does effect ciel, a similar fix could probably work for it.

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.

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.
