Python limited integer squaring to +/- 100, "normal" complex pow beyond that.

This is Python 2.6 (newer version is similar)

>>> z = 3+4j
>>> z100 = z**100
>>> abs(z - z**101/z100), abs(z - z100/z**99)
(2.4565801279300335e-14, 9.9301366129890925e-16)
>>>
>>> z = 4+5j
>>> z100 = z**100
>>> abs(z - z**101/z100), abs(z - z100/z**99)
