NAME
fdim, fdimf, fdiml -- positive difference functions
LIBRARY

SYNOPSIS
#include <math.h> double fdim(double x, double y); float fdimf(float x, float y); long double fdiml(long double x, long double y);

The fdim(), fdimf(), and fdiml() functions return the positive difference between x and y. That is, if x-y is positive, then x-y is returned. If either x or y is an NaN, then an NaN is returned. Otherwise, the result is +0.0. Overflow or underflow may occur if the exact result is not representable in the return type. No other exceptions are raised.
SEE ALSO
