Python throws an error, but numpy.divide(1., 0) will work just fine (and return inf).

I'm not sure why you're saying C throws an error. The behavior of dividing by 0 is undefined by default, but on most machines these days the hardware implements IEE-754 and the C implementation will advertise as implementing IEC 60559, so 1. / 0 will give you inf as well.

Trying to compile a test program with Clang threw errors, and bringing up numpy is disingenuous.

Are you sure you were using floating point math? Compiling 1.0 / 0.0 should not give errors or warnings. 1 / 0 will, on the other hand.
