FERAISEEXCEPT(3M) Mathematical Library Functions FERAISEEXCEPT(3M)

feraiseexcept - raise floating-point exception

#include <fenv.h>
int feraiseexcept(int excepts);

The feraiseexcept() function attempts to raise the supported floating-point exceptions represented by the excepts argument. The order in which these floating-point exceptions are raised is unspecified.

If excepts is 0 or if all the specified exceptions were successfully raised, feraiseexcept() returns 0. Otherwise, it returns a non-zero value.

No errors are defined.

The effect is intended to be similar to that of floating-point exceptions raised by arithmetic operations. Hence, enabled traps for floating-point exceptions raised by this function are taken.
