Hotel Room Calculator. Output is incorrect?

GamerAid (15)
I made this program to calculate hotel expenses. Everything works fine, except the output is rounded off as an integer, when it should be a double. For example, If the input is $225 for roomPrice, 14 for roomNum, 7 for roomDays, and 7.2 for salesTax, the output should be $20091.96. But instead, the output is $20092.

Why is it rounding and displaying as an int? I know it's something simple but I can't figure it out. Am I missing a header file or something?

    total2 = total1 * discount;

    total1 = total1 - total2;

    salesTax = salesTax / 100;

    total2 = total1 * salesTax;

    total1 = total1 + total2;

    cout << "Total billing amount: $" << total1 << endl;

    return 0;
}
lastchance (6980)
cout << "Total billing amount: $" << fixed << setprecision( 2 ) << total1 << endl;

You will need header
#include <iomanip>
in order to use setprecision.
