fmod - floating-point remainder function


SYNOPSIS

       #include <math.h>

       double fmod(double x, double y);


DESCRIPTION

       The  fmod()  function computes the remainder of dividing x
       by y.  The return value is x - n * y, where n is the  quo­
       tient of x / y, rounded towards zero to an integer.


RETURN VALUE

       The  fmod()  function  returns  the remainder, unless y is
       zero, when the function fails and errno is set.


ERRORS

       EDOM   The denominator y is zero.
