Thread: How do I get my answers to out with 2 decimal places?

Hi I have my program working all I need now is to output the answers to 2 decimal places. Could somebody help me out with this? Below is my code.

package assignment2;

import java.text.DecimalFormat;
import java.util.Scanner;

/**

public class PowerSquare {

public static void main(String[] args) {


double num1;
double num2;
double num1a;
double num2a;


Scanner scan = new Scanner(System.in);

System.out.println("Enter 2 numbers");
num1 = scan.nextDouble();



for (double i = num1; i <= num1 {
num1a =(i * i * i);



num2 = scan.nextDouble();
num2 = (num2 < 0 ? -num2 : num2);

for (double a = num2; a <= num2{
num2a =(Math.sqrt(a));
num2a =(Math.round(num2a));


if (num1a > num2a){

System.out.print(num1a);
}
else if (num2a > num1a){

System.out.print(num2a);
}
else if (num2 < 0){

DecimalFormat fmt = new DecimalFormat("#.##");
System.out.println(num2a);
}
System.exit(0);
}







}}}

I still don't really understand? I have been trying for hours and just can't seem to get it right.
