Single.ToString Method in C#

The Single.ToString() method in C# is used to convert the numeric value of this instance to its equivalent string representation.

Syntax

The syntax is as follows −

public override string ToString ();

Example

Let us now see an example −

 Live Demo

using System;
public class Demo {
   public static void Main(){
      float f1 = 10.0f/0.0f;
      float f2 = -3.0f;
      Console.WriteLine("Value1 (String representation) = "+f1.ToString());
      Console.WriteLine("Hashcode for Value1 = "+f1.GetHashCode());
      Console.WriteLine("TypeCode for Value1 = "+f1.GetTypeCode());
      Console.WriteLine("Is Value1 value is positive or negative infinity? = "+Single.IsInfinity(f1));
      Console.WriteLine("Is Value1 NaN? = "+Single.IsNaN(f1));
      Console.WriteLine("Is Value1 a positive infinity? = "+Single.IsPositiveInfinity(f1));
      Console.WriteLine("
Value1 (String representation) = "+f2.ToString());
      Console.WriteLine("Hashcode for Value2 = "+f2.GetHashCode());
      Console.WriteLine("TypeCode for Value2 = "+f2.GetTypeCode());
      Console.WriteLine("Is Value2 value is positive or negative infinity? = "+Single.IsInfinity(f2));
      Console.WriteLine("Is Value2 NaN? = "+Single.IsNaN(f2));
      Console.WriteLine("Is Value2 a positive infinity? = "+Single.IsPositiveInfinity(f2));
   }
}

Output

This will produce the following output −

Value1 (String representation) = ∞
Hashcode for Value1 = 2139095040
TypeCode for Value1 = Single
Is Value1 value is positive or negative infinity? = True
Is Value1 NaN? = False
Is Value1 a positive infinity? = True
Value1 (String representation) = -3
Hashcode for Value2 = -1069547520
TypeCode for Value2 = Single
Is Value2 value is positive or negative infinity? = False
Is Value2 NaN? = False
Is Value2 a positive infinity? = False

Example

Let us now see another example −

using System;
public class Demo {
   public static void Main(){
      float f1 = 5.0f/0.0f;
      float f2 = 0.0f/0.0f;
      Console.WriteLine("Value1 (String representation) = "+f1.ToString());
      Console.WriteLine("Hashcode for Value1 = "+f1.GetHashCode());
      Console.WriteLine("TypeCode for Value1 = "+f1.GetTypeCode());
      Console.WriteLine("Is Value1 value is positive or negative infinity? = "+Single.IsInfinity(f1));
      Console.WriteLine("Is Value1 NaN? = "+Single.IsNaN(f1));
      Console.WriteLine("Is Value1 a negative infinity? = "+Single.IsNegativeInfinity(f1));
      Console.WriteLine("
Value2 (String representation) = "+f2.ToString());
      Console.WriteLine("Hashcode for Value2 = "+f2.GetHashCode());
      Console.WriteLine("TypeCode for Value2 = "+f2.GetTypeCode());
      Console.WriteLine("Is Value2 value is positive or negative infinity? = "+Single.IsInfinity(f2));
      Console.WriteLine("Is Value2 NaN? = "+Single.IsNaN(f2));
      Console.WriteLine("Is Value2 a negative infinity? = "+Single.IsNegativeInfinity(f2));
   }
}

Output

This will produce the following output −

Value1 (String representation) = ∞
Hashcode for Value1 = 2139095040
TypeCode for Value1 = Single
Is Value1 value is positive or negative infinity? = True
Is Value1 NaN? = False
Is Value1 a negative infinity? = False
Value2 (String representation) = NaN
Hashcode for Value2 = -4194304
TypeCode for Value2 = Single
Is Value2 value is positive or negative infinity? = False
Is Value2 NaN? = True
Is Value2 a negative infinity? = False
