Detailed Description

We assume that errors during floating-point operations aren't terminal errors.

So we dont't try to prevent domain errors (e.g. square root of a negative number) or range error (e.g. pow(10.0, 1e6)) checking arguments beforehand (domain errors could be prevented by carefully bounds checking the arguments before calling functions and taking alternative action if the bounds are violated; range errors usually cannot be prevented, as they are dependent on the implementation of floating-point numbers, as well as the function being applied). Instead we detect them and take alternative action (usually returning an empty value).
