Thread: Please Help!

Okay, I'm a total noob at java and am writing a simple program for a class. The program works,
but not as I want it to. I really need it to display the total decimals for the totalProfit and totalCost outputs. Also, if it's
not too much trouble I'd like to know what I'm doing wrong.

***********HERE IS THE CODE***********

// Created By: Russell on 02/09/2019
// Program that acquires input of total amount of milk, then calculates and 
// displays the amounts of cartons produced, cost to create the milk and 
// total profits gained
package exercise14;
 
import java.util.*;
 
public class exercise14 {
    static Scanner console = new Scanner(System.in);
        //declare constants
    static final double CARTON = 3.78;
    static final double COST = 0.38;
    static final double PROFIT = 0.27;
 
    public static void main(String[] args) {
 
        //declare variables        
        int liter;
        int cartonsNeeded;
        double totalCost;
        double totalProfit;
 
        //obtain information
        System.out.println("Enter liters of milk processed: ");
        liter = console.nextInt();
 
        //calculate
       cartonsNeeded = (int) (liter/CARTON);
       totalCost = (int) (liter*COST);
       totalProfit = (int) (cartonsNeeded*PROFIT);
 
       //display results
       System.out.println("You entered " +liter +" liters.");
       System.out.println("You require " +cartonsNeeded +" cartons.");
       System.out.println("Total Cost: $" +totalCost);
       System.out.println("Total Profits: $" +totalProfit);
 
    }
 
}

here are my outputs. (Total Profits should be somewhere around $7.0200000000000005)

run:
Enter liters of milk processed:
100
You entered 100 liters.
You require 26 cartons.
Total Cost: $38.0
Total Profits: $7.0
BUILD SUCCESSFUL (total time: 2 seconds)

what I'm doing wrong.

Please explain. Copy and paste here any output that shows the what you are talking about. Add some comments describing what is wrong and show the desired output.

Please edit your post and wrap your code with code tags:

[code]
**YOUR CODE GOES HERE**
[/code]

to get highlighting and preserve formatting.

Ok, so you are saying that Total Profits should be $7.0200000000000005 instead of 7.0
Where in the code is the variable: totalProfit assigned a value?
Can casting to an int truncate the desired value?
Try removing the cast to int
