    Default Rounding Question

    Hey everybody!

    How would I convert the output given to this variable (which is double) into a number rounded to teh nearest 2 numbers after the decimal point.

    PST = ((TRSA * (1-SD/100) * PST));

    I need it to the nearest number after two decimal points as it's having to do with money.

    public class z
    {
        public static void main(String [] args)
        {
            double x = 3.14159265358979323846;
            System.out.printf("x = %.16f\n", x);
            System.out.printf("x = %.2f\n\n", x);
     
            double y = 2.7182818284590452354;
            System.out.printf("y = %.16f\n", y);
            System.out.printf("y = %.2f\n", y);
        }
    }


    Output:

    x = 3.1415926535897930
    x = 3.14

    y = 2.7182818284590450
    y = 2.72


    Cheers!
