Description

Tests for simple math functions.

Theoretically we'd like all math functions to match exactly, even in floating-point, but that is not realistic without excessive corrections to get the last ulp right - so in practice we target 1-2 ulp, which is VERY tight. However, to avoid worrying users we are a bit more generous and use 5-10 ulp as tolerance for the actual tests users will run through.
