SYNOPSIS


.In math.h double fdim "double x" "double y" float fdimf "float x" "float y" long double fdiml "long double x" "long double y"

DESCRIPTION

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 iff the exact result is not representable in the return type. No other exceptions are raised.
