Thread: How do I generate a random float/decimal?

This works. I just wrote it now so it isn't the best, plus it is kinda expensive.

Code:

#include <iostream>
#include <cstdlib>
#include <math.h>
#include <time.h>

int main(void) {
	using namespace std;
	srand(time(NULL));
	float r;
	int i;
	
	for(;;) {
		i = rand();
		r = (i-sqrtf(i))/10000;
		cout << r << endl;
	}
		

	return 0;
}

stupid smilies...

Just make a random integer then devide it by another number.
Then you can store it in a float or double...
