    Default Math.round...I need help understanding what I am doing wrong and why it's not working

    Hi, I don't understand what am I doing wrong, I just can't get the right answer no matter what I change. Here is the code:

     
    import java.io.*;
    import static java.lang.System.*;
     
    import java.util.Scanner;
     
     
    import java.lang.Math;
     
     
    class Assignment2 {
     
         public static void main (String str[]) throws IOException {
             Scanner scan = new Scanner(System.in);
     
     
     
     
     
     
           System.out.println("Please enter two decimal");
     
     
     
     
          double x = scan.nextDouble();
         double y =scan.nextDouble();
          int temp = (int)Math.round(100*x);
     
         System.out.println(1.0*(200-temp)/100);
         System.out.println((y - x));
     
     
     
     
     
     
     
         }
     
    }

    I am getting .53 and I should be getting 0.527
    Anyone explanation and/or feedback, will be greatly appreciated. I have tried everything but can't get 0.527

    Thanks
    Hilda

    Try to compress your code a little bit, so it will be better to read.

    I'm not sure if you need to import all that stuff, try looking at that.
