How to round a double to 2 decimal places?


If the value is 300.1234, it should be formatted to 300.12. If it is 300, then it should be 300.00



public static double round(double val, int places)


    if (places < 0) throw new IllegalArgumentException();

    long fact = (long) Math.pow(10, places);

    val = val * fact;

    long tmp = Math.round(val);

    return (double) tmp / fact;
