[New-bugs-announce] [issue31980] Special case log(x, 2), log(x, 10) and pow(2, x)

[Serhiy Storchaka]

New submission from Serhiy Storchaka <storchaka+cpython at gmail.com>:

C99 provides functions log2(), log10() and exp2(). Is it worth to special case math.log(), math.pow() and built-in pow() for using these functions? log2(x) can be more accurate than log(x)/log(2).

There are math.log2() and math.log10(), but not math.exp2().
