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.
fdim
(), fdimf
(), and
fdiml
() functions conform to ISO/IEC
9899:1999 (“ISO C99”).
