read a random number into a float between the range of 0 and 100, then divide by 100 to get a number from 0 to 0.9999

Yes, what Ancient Dragon sead will work fine, to save some time you could define it as a macro.

#include<iostream>

#define rand_f(n)   (((rand()%10000)/10000.0f)*n)

int main() {
	for (int i = 0; i < 100; i++) {
		std::cout << rand_f(1) << '\n';
	}
	std::cin.ignore();
	return 0;
}
