Formatting a double

[squizzel]

Ok so I have this number 1.4316557653333 333E9 and I need to format this number so I can print out 1431 million 655 thousand and 765

Here is my curent code:

 

import java.util.*;
public class numberthree {

	public static void main(String[] args) {
		
		double DAY , space , mill , thou , hund; 
		
		Scanner keyboard = new Scanner(System.in);
		
		System.out.println("Please input the number of days MyMail has been running :");
		DAY = keyboard.nextDouble();
		
		space =  ( (( 512 * Math.pow(2, 20) )/ 15 ) * DAY ) + (1024  * Math.pow(2, 20)) ;
		
		
		System.out.println(space);
		
		 	mill = space / 1000000;
		 	thou = space % 1000000;
		 	hund = space % 1000;
		
		
		System.out.printf("Email storage space (in bytes): " +  "%.2f" , mill + "million" +  thou +  "thousand" + hund);
	
		
	
	
	
	
	
	}



}

Thanks for the help!
