Convert from Object to Float not working c++

Question

I'm trying to convert a object to a float, but it doesn't seems to work the way I want.

int main()
{
  Fraction A(20,6);
  float E;  
  E = A;
  cout << E << endl;
}

I already did a type convert operator inside the class

operator float () const     
    {           
        return static_cast<float>(num/den);  //Being num and den private members, 20 and 6 in this case. 
    }

When I run the program, the result is 3 (with no decimal places). Any help?

You haven't provided the types for num and dem, but I bet they're integral. Cast one of them before you divide and see what you get. — twsaef, Mar 08 '16 at 22:08
Maybe: `return float(num)/den` (but you do not provide enough information) — , Mar 08 '16 at 22:09

I can't see your code, but based on the behavior you're observing, is it possible that num and den are defined as int data types? If so, num/den is being treated as integer division, and therefore resulting in the result being truncated.
