> You know what? Mac OS X log2 is less accurate than Python log2! That doesn't surprise me much. Though it's probably still true that log2 from OS X is more accurate than our log2 for some other values. It's just that getting the answer wrong for a power of 2 is a 'high-visibility' error. Testing log2 sounds long-winded and error-prone. I'd suggest just marking that test as an expected failure on Tiger. BTW, I don't see any such failure on Snow Leopard.
