FDIM(3)                    BSD Programmer's Manual                     FDIM(3)

NAME

     fdim, fdimf, fdiml - positive difference functions

LIBRARY

     libm

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);

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.

SEE ALSO

     fabs(3), fmax(3), fmin(3), math(3)

STANDARDS

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