FMOD(3)                 NetBSD Library Functions Manual                FMOD(3)


NAME

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


LIBRARY

     Math Library (libm, -lm)


SYNOPSIS

     #include <math.h>

     double
     fmod(double x, double y);

     float
     fmodf(float x, float y);

     long double
     fmodl(long double x, long double y);


DESCRIPTION

     The fmod() function computes the floating-point remainder of x/ y.


RETURN VALUES

     The fmod(), fmodf(), and fmodl() 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 implementa-
     tion-defined.


SEE ALSO

     math(3)


STANDARDS

     The fmod() function conforms to ANSI X3.159-1989 (``ANSI C89'').
