Float Equal Function

example:

=========
#include <fequal.h>
#include <stdio.h>

int
main(void)
{
	float f = 0.1;
	float sum = 0;

	int i;
	for (i = 0; i < 10; i++)
		sum += f;
	printf("sum: %1.15f, f*10: %1.15f\n", sum, f*10);
	printf("sum == f*10: %d\n", sum == f*10);
	printf("fequal(sum, f*10): %d\n", fequal(sum, f*10));
	return 0;
}
=========

fequal() will work well for most case
if not for you,just use another two function from fequal.h
