Ok, so I'm just getting the hang of this floating point thing and I decided to write a couple of quick programs to illustrate the difference between that and int. I got it to divide 5/2 and get 2 with the variable being an integer but this code isn't working to make it equal to 2.5:


#include<stdio.h>

float main()
{
float x;

x=5/2;

printf("%f", x);
}

Any help please?

5/2 is ALWAYS 2, regardless of the data type being assigned to.
5/2.0 is 2.5.

Oh OK, thanks very much

Also, it's int main and not float. You can read more about that here and here.
