How to type cast int division to floating point?

#include <iostream>
#include <stdio.h>
using namespace std;
 
int main() {
 
 float f=static_cast<float>(5/2);
 printf("%f",f);
 
 return 0;
}

The answer is always 2.0. I searched before asking but couldn't find the answer.

This works on my compiler:

#include <iostream>
#include <stdio.h>
using namespace std;

int main() {

 float f=(float)5/(float)2;
printf("%f",f);

return 0;
}
