Single.Equals() Method in C# with Examples

Last Updated : 01 May, 2019

Single.Equals() Method is used to get a value which indicates whether the two instances of Single represents the same value or not. There are 2 methods in the overload list of this method as follows:

Equals(Single) Method

Equals(Object) Method

Single.Equals(Single) Method

This method is used to return a value indicating whether this instance and a specified Single object represent the same value.

Syntax: public bool Equals (float obj); Here, it takes a Single object to compare to this instance. Return Value: This method returns true if obj is equal to this instance otherwise, false.

Below programs illustrate the use of Single.Equals() Method: Example 1:

csharp

// C# program to demonstrate the // Single.Equals(Single) Method using System; using System.Globalization;  class GFG {      // Main Method     public static void Main()     {         // Declaring and initializing value1         float value1 = 10.5f;          // Declaring and initializing value2         float value2 = 20.6f;          // using Equals(Single) method         bool status = value1.Equals(value2);          // checking the status         if (status)             Console.WriteLine("{0} is equal to {1}",                                     value1, value2);         else             Console.WriteLine("{0} is not equal to {1}",                                         value1, value2);     } }

Output:

  10.5 is not equal to 20.6

Example 2:

csharp

// C# program to demonstrate the // Single.Equals(Single) Method using System; using System.Globalization;  class GFG {      // Main Method     public static void Main()     {          // calling get() method         get(5f, 5f);         get(5.5f, 4.5f);         get(10f, 10f);         get(7.5f, 19.5f);     }      // defining get() method     public static void get(float value1,                             float value2)     {          // using Equals(Single) method         bool status = value1.Equals(value2);          // checking the status         if (status)             Console.WriteLine("{0} is equal to {1}",                                     value1, value2);         else             Console.WriteLine("{0} is not equal to {1}",                                         value1, value2);     } }

Output:

  5 is equal to 5  5.5 is not equal to 4.5  10 is equal to 10  7.5 is not equal to 19.5

Single.Equals(Object) Method

This method is used to returns a value indicating whether this instance is equal to a specified object or not.

Syntax: public override bool Equals (object obj); Here, it takes an object to compare with this instance. Return Value: This method returns true if obj is an instance of Single and equals the value of this instance otherwise, false.

Below programs illustrate the use of the above-discussed method: Example 1:

csharp

// C# program to demonstrate the // Single.Equals(Single) Method using System; using System.Globalization;  class GFG {      // Main Method     public static void Main()     {         // Declaring and initializing value1         float value1 = 10.5f;          // Declaring and initializing value2         object value2 = 3 / 36;          // using Equals(object) method         bool status = value1.Equals(value2);          // checking the status         if (status)             Console.WriteLine("{0} is equal to {1}",                                     value1, value2);         else             Console.WriteLine("{0} is not equal to {1}",                                         value1, value2);     } }

Output:

  10.5 is not equal to 0

Example 2:

csharp

// C# program to demonstrate the // Single.Equals(object) Method using System; using System.Globalization;  class GFG {      // Main Method     public static void Main()     {         // calling get() method         get(5f, new Object());         get(5.5f, (float)5.5);         get(10f, 10);         get(7.5f, 2 / 5);     }      // defining get() method     public static void get(float value1,                          object value2)     {          // compare both float value         // using Equals(object) method         bool status = value1.Equals(value2);          // checking the status         if (status)             Console.WriteLine("{0} is equal to {1}",                               value1, value2);         else             Console.WriteLine("{0} is not equal to {1}",                               value1, value2);     } }

Output:

  5 is not equal to System.Object  5.5 is equal to 5.5  10 is not equal to 10  7.5 is not equal to 0
