FMOD(3) NEWLIB FMOD(3)NAME
1.24 `fmod', `fmodf'--floating-point remainder (modulo)
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 (X modulo Y).
RETURNS
The `fmod' function returns the value X-I*Y, for the largest integer I
such that, if Y is nonzero, the result has the same sign as X and mag‐
nitude less than the magnitude of Y.
`fmod(X,0)' returns NaN, and sets `errno' to `EDOM'.
You can modify error treatment for these functions using `matherr'.
PORTABILITY
`fmod' is ANSI C. `fmodf' is an extension.
SEE ALSO
fmod is part of the library. The full documentation for is maintained
as a Texinfo manual. If info and are properly installed at your site,
