How to check if two double values are equal in C#

Overview

Two double objects are equal if they both have the same values. The Double.Equals() method in C# determines if two double objects are equal. It returns true if they are equal and false otherwise.

// use System
using System;
// create class
class DoubleEquality
{
    // main method
    static void Main()
    {
      // create double values
      double d1 = 343.13423;
      double d2 = 1.4545;
      double d3 = 5.7;
      double d4 = d3 * 1 / 1;
      // check equality
      bool b1 = d1.Equals(d2);
      bool b2 = d2.Equals(d3);
      bool b3 = d3.Equals(d4);
      bool b4 = d4.Equals(d3);
      // print results
      Console.WriteLine(b1);  // False
      Console.WriteLine(b2);  // False
      Console.WriteLine(b3);  // True
      Console.WriteLine(b4);  // True
    }
}
