floating-point division by zero signals the FE_DIVBYZERO exception.
you can test this via fetestexcept(FE_DIVBYZERO).

integer operations must not affect fenv status flags so integer
division by zero does not do that.

if you want to *trap* division by zero, there is no reliable way
to do that in c (this is not related to particular cpus though).
