The fpu exception mask is always global for an entire program. It is not possible to disable it only for the code in one single library.

It's not C programmers that do it. It's the C library that does it in its startup code, or maybe even the operating system when creating a new process. But as a result, indeed almost no single C program takes invalid floating point operations into account (which is bad practice, because e.g. floating point operations involving NaNs can be extremely slow).

You can try, but he probably won't care.
