How to get a floating point result from dividing two integers

Question

I can't get float value from int/int.

float rs;
int a=10;
int b=3;
rs=(float)a/b;

Result : 3.0 . I need 3.333 Thank!

Answer 1

Testing your code, it does indeed give 3.333, because the typecast takes precedence... did you execute some other code?

---

Another possible option is to typecast b.

rs = a / (float)b;

You could also typecast a, but you'd need an extra set of parenthesis.

Here's an ideone demo.

Answer 2

EDIT: The cast has priority:

rs = (float) a / b;

Or,

float new_a = a;
rs = new_a / b;
