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 −
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
