calculate different aspects of a water bill (such as water usage cost

and sewer usage costs) and I have managed to get it working, except I

am suppose to round the numbers in the results, and I don't know how

to do that with doubles. Here are the directions of the assignment

and then what i have so far.:

The user will enter the number of gallons of water they used during

the billing period (whole number). after this has been entered, the

following must be displayed, all as currency:

Base charge: $15.79

Water usage: $0.27 per 100 gallons

Sewer usage: $1.49 per 1000 gallons

Subtotal

Tax: 6% of subtotal

Total

my code so far:

/**

* @(#)try1.java

*

* try1 application

*

* @author

* @version 1.00 2008/2/11

*/

import java.util.*;

import javax.swing.*;

public class try1 {

public static void main(String[] args) {

Scanner input = new Scanner(System.in);

System.out.print("Please enter the amount of gallons used: ");

int gal = input.nextInt();

int galhund = gal/100; //amount rounded to the hundreds

int galthous = gal/1000; //amount rounded to the thousands

double base = 15.79; //base service charge

double water = galhund*0.27; //water usage charge

double sewer = galthous*1.49; //sewer usage charge

double sub = base+water+sewer; //subtotal

double tax = sub*.06; //subtotal times 6% tax

double total = sub+tax; //total due

System.out.println("Base Service $" + base);

System.out.println("Water Usage $" + water);

System.out.println("Sewer Usage $" + sewer);

System.out.println("Subtotal $" + sub);

System.out.println("Tax $" + tax);

System.out.println("Total Due $" + total);

}

}

Currently everything seems to calculate correctly, except it comes out

looking like this:

Please enter the amount of gallons used: 12345

Base Service $15.79

Water Usage $33.21

Sewer Usage $17.88

Subtotal $66.88

Tax $4.0127999999999995 ( <-- need to round to 2

decimals )

Total Due $70.8928 ( <-- need to round to 2 decimals )

Process completed.
