Description

Checks the the given doubles if they are equals - which means they are closer than a predefined epsilon value, because comparing two doubles directly is a bad practice.

Demo Code


//package com.java2s;

public class Main {
    private static final double EPSILON = 0.0001;

    /**//from  w w  w . jav a  2s  . c om

     * @param a one of the values to be checked
     * @param b the other value to be checked
     * @return true if the two values are close enough to call them equals
