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);
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.
