    like 12.04 or 12.045 etc?

    cout.setf(ios::showpoint);
    cout.setf(ios::fixed);
    cout.precision(2);

    The cout.precision line is what you want the rounding to. 2 means to the nearest hundredth, 3 to the nearest thousandth, etc

    Maybe you mean setprecision(), where setprecision(0) means that there are no decimal points...
    none...
