FMOD(3) Linux Programmer's Manual FMOD(3)NAME
fmod, fmodf, fmodl - floating-point remainder function
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);
Link with -lm.
DESCRIPTION
The fmod() function computes the remainder of dividing x by y. The
return value is x - n * y, where n is the quotient of x / y, rounded
towards zero to an integer.
RETURN VALUE
The fmod() function returns the remainder, unless y is zero, when the
function fails and errno is set.
ERRORS
EDOM The denominator y is zero.
CONFORMING TO
SVr4, 4.3BSD, C89. The float and long double variants are C99 require‐
ments.
