New restriction on pow(x, y, z): If z is not None, x and y must be of
...
integer types, and y must be >= 0. See discussion at

Revert the previous patch to test_pow.py and move the test to test_unary.py
...
based on a suggestion from Tim Peters; also make sure that we're really
doing exponentiation and not multiplication.

Make the test pass now that 10**-15 returns a float instead of raising

an exception.

Update the code to better reflect recommended style:
...
Use != instead of <> since <> is documented as "obsolescent".
Use "is" and "is not" when comparing with None or type objects.

SF bug 115831 and Ping's SF patch 101751, 0.0**-2.0 returns inf rather than
...
raise ValueError. Checked in the patch as far as it went, but also changed
all of ints, longs and floats to raise ZeroDivisionError instead when raising
0 to a negative number. This is what 754-inspired stds require, as the "true
result" is an infinity obtained from finite operands, i.e. it's a singularity.
Also changed float pow to not be so timid about using its square-and-multiply
algorithm. Note that what math.pow does is unrelated to what builtin pow
does, and will still vary by platform.
