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

NAME
fmod, fmodf, fmodl — floating-point remainder functions

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(), fmodf(), and fmodl() functions compute the floating-point
remainder of x/ y.

RETURN VALUES
If y is non-zero, the fmod(), fmodf(), and fmodl() functions return the
value x-i*y, for some integer i, such that the result has the same sign
as x and magnitude less than the magnitude of y.  If y is zero, a NaN is
produced.

math(3)

STANDARDS
The fmod(), fmodf(), and fmodl() functions conform to ISO/IEC 9899:1999
(“ISO C99”).
