Sample Solution:

Java Code:

import java.util.Scanner;
public class Exercise6 {

    
  public static void main(String[] args)
    {
        Scanner in = new Scanner(System.in);

        System.out.print("Input floating-point number: ");
        double x = in.nextDouble();
        System.out.print("Input floating-point another number: ");
        double y = in.nextDouble();

        x = Math.round(x * 1000);
        x = x / 1000;

        y = Math.round(y * 1000);
        y = y / 1000;

        if (x == y)
        {
            System.out.println("They are the same up to three decimal places");
        }
        else
        {
            System.out.println("They are different");
        }
    }
}

Sample Output:

Input floating-point number: 1256                                                             
Input floating-point another number: 3254                                                             
They are different
