Try this proven formulae

Code:
private double roundup(double a) {
    // To round up any figure
    return java.lang.Math.floor(a + 0.99);
}

This code allows you to round a double value to 2 decimal places using DecimalFormat.

You can increase the decimal places by adding an extra #. For example DecimalFormat("#.###"); rounds to 3 decimal places.

import java.text.*;

public class DecimalPlaces {

public static void main(String[] args) {

double d = 1.234567;
DecimalFormat df = new DecimalFormat("#.##");
System.out.print(df.format(d));
}

}
