Sure, it wouldn't harm. I'd expect that all these cases are already being 
tested indirectly by some part of test_math, but direct tests are better.

Note that Python still can't/won't assume IEEE 754 floating-point, so if the 
tests use special values like infinities and nans, or other IEEE 754 
assumptions, then they should be guarded by a suitable "skipIf" decorator.
