NAME
       fmod, fmodf, fmodl - floating-point remainder function

SYNOPSIS
       #include 

       double fmod(double x, double y);
       float fmodf(float x, float y);
       long double fmodl(long double x, long double y);

       Link with -lm.

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.

CONFORMING TO
       SVr4, 4.3BSD, C89.  The float and long double variants are C99 require
       ments.
