Decimal Comparator

 Write a method areEqualByThreeDecimalPlaces with two parameters of double

The method should return boolean and it needs to return true if two double decimal numbers are the same up to three decimal places. Otherwise, return false

Example

       areEqualByThreeDeciamlPlaces(-3.125,-3.1259)-----> true

       areEqualByThreeDeciamlPlaces(-3.125,-3.139)----> false


Soln:   package com.cnc;


public class Main {


    public static void main(String[] args) {

        System.out.println(areEqualByThreeDecimalPlaces(-3.125, -3.1259));
    }

    public static boolean areEqualByThreeDecimalPlaces(double firstNumber, double secondNumber) {


        if ((int) (firstNumber * 1000) == (int) (secondNumber * 1000)) {
            return true;
        }
        return false;
    }
}
