fmod, fmodf, fmodl - floating-point remainder function

#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.
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.
The
fmod() function returns the remainder, unless
y is zero, when
the function fails and
errno is set.
- EDOM
- The denominator y is zero.
SVID 3, POSIX, BSD 4.3, ISO 9899. The float and the long double variants are C99
requirements.
