[issue44344] Documentation for pow() should include the possibility of complex numbers as a return type

[Erik Y. Adams]

Erik Y. Adams <erikyadams at outlook.com> added the comment:

I still think the most important aspect of this is that pow() will return complex numbers, contrary to what is implied by the statement I quoted at the beginning of this thread. 

Perhaps we should just borrow from the documentation for the power operator, which says:

Raising 0.0 to a negative power results in a ZeroDivisionError. Raising a negative number to a fractional power results in a complex number. (In earlier versions it raised a ValueError.)
