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


NAME

     fmod, fmodf -- 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);


DESCRIPTION

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


RETURN VALUES

     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 mag-
     nitude less than the magnitude of y.  If y is zero, whether a domain
     error occurs or the fmod() function returns zero is implementation-
     defined.


SEE ALSO

     math(3)


STANDARDS

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