    Default Making a tax program

    The code is below and the problem I am having is the numbers after the decimal won't add together for the total I am teaching myself java through liang's 10th edition book and I took one of the sample programs further than what was shown. The one in the book only shows the tax amount I simply wanted to make it so that the purchase amount and the tax amount would add together


    package javalearning;
    import java.util.Scanner;



    public class FindingTax {
    public static void main(String[] args){
    Scanner input = new Scanner(System.in);
    System.out.print("Enter Purchase amount: ");
    double purchaseAmount = input.nextDouble();
    double taxAmount = purchaseAmount * 0.0825;
    System.out.println("Sales tax is $" + (int)(taxAmount * 100) /
    100.0);
    double taxTotal =(int) ((taxAmount * 100) / 100.0);
    double TotalAmount = ((double)(taxTotal * 1.00) + purchaseAmount);

    System.out.println("The total amount to pay is:" + TotalAmount);
    }
    }


    This is the result

    run:
    Enter Purchase amount: 125.25
    Sales tax is $ 10.33
    The total amount to pay is: 135.25
    BUILD SUCCESSFUL (total time: 5 seconds)

    Any and all help is very appreciated.

    Please edit your post and wrap your code with code tags:
    [code=java]
    YOUR CODE GOES HERE
    [/code]
    to get highlighting and preserve formatting.

    make it so that the purchase amount and the tax amount would add together
    Can you explain what that means? Perhaps an example of the desired output would help.
    If you don't understand my answer, don't ignore it, ask a question.

    As Norm said as above, use the code tags. So you're asking the numbers won't add up in decimal form? Well thats because you're casting them to an integer.
