C Language Standard Math Single precision and long double precision floating-point remainder: fmodf(), fmodl()
Example
C99
These functions returns the floating-point remainder of the division of x/y. The returned value has the same sign as x.
Single Precision:
#include <math.h> /* for fmodf() */
#include <stdio.h> /* for printf() */
int main(void)
{
float x = 10.0;
float y = 5.1;
float modulus = fmodf(x, y);
printf("%f\n", modulus); /* lf would do as well as modulus gets promoted to double. */
}
Output:
4.90000
Double Double Precision:
#include <math.h> /* for fmodl() */
#include <stdio.h> /* for printf() */
int main(void)
{
long double x = 10.0;
long double y = 5.1;
long double modulus = fmodl(x, y);
printf("%Lf\n", modulus); /* Lf is for long double. */
}
Output:
4.90000
