Oops, forgot one part of the doc definition in the proposed additional
tests:
for x in range(-65000, 65000):
k = x.numbits()
assert k == len(bin(x).lstrip('-0b'))
if x > 0:
assert 2 ** (k-1) <= x < 2**k
assert k == 1 + math.floor(math.log(x) / math.log(2))
elif x == 0:
assert k == 0
else:
assert k == (-x).numbits()
