How to have decimals in calculator?

[AidanShow13]

So I just wrote my first project (been coding for 2 days now and constantly wanting to learn) which was a calculator and it's working great now but when i use division and the quotient isn't an integer it just rounds down. for example 5/3 was 1. Please tell me if there is a way to have decimals. Here is my division section of my calculator:

  else if (operation == "div")
{
        cout << "Please enter a number \n";
        cin >> g;
        cout << "Please enter another number \n";
        cin >> z;
        quot = g / z;
        cout << quot << endl;
}

Integer division truncates toward 0. It will retain no portion of the decimal remainder.

If you wish to have decimals, use either double or float.
