NAME
       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 quotient 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.
