```FMOD(3)			 BSD Library Functions Manual		       FMOD(3)

NAME
fmod — floating-point remainder function

SYNOPSIS
#include <math.h>

double
fmod(double x, double y);

float
fmodf(float x, float y);

DESCRIPTION
The fmod() and fmodf() functions compute the floating-point remainder of
x/ y.

Specifically, the 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 magni‐
tude less than the magnitude of y.

SPECIAL VALUES
fmod(�0, y) returns �0 for y not zero.

fmod(x, y) returns a NaN and raises the "invalid" floating-point excep‐
tion for x infinite or y zero.

fmod(x, �infinity) returns x for x not infinite.

math(3)

STANDARDS
The fmod() and fmodf() functions conform to ISO/IEC 9899:1999(E).
