FMOD(3) FreeBSD 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.

STANDARDS
The fmod(), fmodf(), and fmodl() functions conform to ISO/IEC 9899:1999
("ISO C99").
HISTORY
An fmod() function first appeared in Version 5 AT&T UNIX.
