Double.GetHashCode() Method in C#

Last Updated : 18 Jan, 2023

Double.GetHashCode() Method is used to return the hash code for this instance.

Syntax: public override int GetHashCode ();

Return Value: This method returns a 32-bit signed integer hash code.

Below programs illustrate the use of Double.GetHashCode() Method:

Example 1:

csharp

// C# program to demonstrate the // Double.GetHashCode() Method using System; using System.Globalization;  class GFG {      // Main Method     public static void Main()     {          // Declaring and initializing value1         double value1 = 10d;          // getting the HashCode         // using GetHashCode() method         int value = value1.GetHashCode();          // Display the HashCode         Console.WriteLine(&quot;HashCode is {0}&quot;, value);     } }

Output:

HashCode is 1076101120

Example 2:

csharp

// C# program to demonstrate the // Double.GetHashCode() // Method using System; using System.Globalization;  class GFG {      // Main Method     public static void Main()     {         // calling get() method         get(5d);         get(5.5d);         get(10d);         get(7.5d);     }      // defining get() method     public static void get(double value1)     {          // getting the HashCode         // using GetHashCode() method         int value = value1.GetHashCode();          // Display the HashCode         Console.WriteLine(&quot;HashCode is {0}&quot;, value);     } }

Output:

HashCode is 1075052544 HashCode is 1075183616 HashCode is 1076101120 HashCode is 1075707904
