FMOD(3) OpenBSD Programmer's Manual FMOD(3)NAME
fmod, fmodf - floating-point remainder functions
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. The
fmodf() function is a single precision version of fmod().
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
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.
SEE ALSOmath(3)STANDARDS
The fmod() function conforms to ANSI X3.159-1989 (``ANSI C'').
