[New-bugs-announce] [issue36415] [math] Implement pow2 function

[Марат Нагаев]

New submission from Марат Нагаев <sidorovmarat1995 at gmail.com>:

Hello.
I want to implement pow2 function special for powers of 2.
pow2 works 110 times faster if we pow 4 to 10**6
pow2 implementaion on Python:
def pow2(a,b):
p=log2(a)*b
if not p.isinteger():
raise TypeError('a isn't power of 2!')
return 1«p
