NAME    [Toc]    [Back]

     fmod, fmodf - floating-point remainder function

LIBRARY    [Toc]    [Back]

     Math Library (libm, -lm)

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.

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 implementationdefined.

SEE ALSO    [Toc]    [Back]

STANDARDS    [Toc]    [Back]

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