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.
