Overview
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 , then an 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.
