| Summary | #include <math.h> double fmod ( double x, /* value to calculate modulo for */ double y); /* integer portion of modulo */ |
| Description | The fmod function returns a value f such that f has the same sign as x, the absolute value of f is less than the absolute value of y, and there exists an integer k such that: k * y + f = x If the quotient x / y cannot be represented, the result is undefined. |
| Return Value | The fmod function returns the floating-point remainder of x / y. |
| Example |
#include <math.h>
#include <stdio.h> /* for printf */
void tst_fmod (void) {
float f;
f = fmod (15.0, 4.0);
printf ("fmod (15.0, 4.0) = %f\n", f);
}
