of one or more of the exception names defined in fenv.h
.

-1 when called from a function whose default floating-point format is hexadecimal,
that is, one compiled without the bfp
option.
A program which calls fesettrapenable
must use the standard FENV_ACCESS pragma in an enclosing scope, or the effects
are unpredictable.
