[issue35637] Factorial should be able to evaluate float arguments

See related discussion in issue #33083.

Are you aware that `math.gamma` and `math.lgamma` exist? These already provide the ability to compute the "factorial" of a non-integral input.

I'd be opposed to extending math.factorial to accept non-integral floats.
