NAME    [Toc]    [Back]

     fmod, fmodf - floating-point remainder functions

SYNOPSIS    [Toc]    [Back]

     #include <math.h>

     double
     fmod(double x, double y);

     float
     fmodf(float x, float y);

DESCRIPTION    [Toc]    [Back]

     The fmod() function computes the floating-point remainder of
x/ y.  The
     fmodf() function is a single precision version of fmod().

RETURN VALUES    [Toc]    [Back]

     The fmod() and fmodf() functions return the value x-i*y, for
some integer
     i such that, if y is non-zero, the result has the same  sign
as x and magnitude
  less than the magnitude of y.  If y is zero, whether
a domain error
 occurs or the fmod() function returns zero is  implementation-defined.

STANDARDS    [Toc]    [Back]

     The  fmod()  function  conforms  to ANSI X3.159-1989 (``ANSI
C'').
