C Reference function fmod()

Usage of fmod():

double fmod(double x, double y);

Return value:

There is no range limit on the return value. If y is zero,
then either a range error will occur or the function will return zero (this can differ per implementation.)

Source code example of fmod():

	#include<stdio.h>
	#include<math.h>

	main()
	{
		printf ("fmod of 2.5 / 2 is %lf\n", fmod(2.5,2));
		return 0;
	}

Output of the fmod example program above:

	fmod of 2.5 / 2 is 0.500000
