Single.IsInfinity() Method in C# with Example
The Single.IsInfinity() method in C# is used to return a value indicating whether the specified number evaluates to negative or positive infinity.
Syntax
The syntax is as follows −
public static bool IsInfinity (float val);
Above, val is a single-precision floating-point number.
Example
Let us now see an example −
using System;
public class Demo {
public static void Main(){
float f1 = 19.3f;
float f2 = Single.MaxValue;
Console.WriteLine("Value1 = "+f1);
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("
Value2 = "+f2);
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));
}
}Output
This will produce the following output −
Value1 = 19.3 Hashcode for Value1 = 1100637798 TypeCode for Value1 = Single Is Value1 value is positive or negative infinity? = False Value2 = 3.402823E+38 Hashcode for Value2 = 2139095039 TypeCode for Value2 = Single Is Value2 value is positive or negative 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 = Single.MinValue;
Console.WriteLine("Value1 = "+f1);
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("
Value2 = "+f2);
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));
}
}Output
This will produce the following output −
Value1 = ∞ Hashcode for Value1 = 2139095040 TypeCode for Value1 = Single Is Value1 value is positive or negative infinity? = True Value2 = -3.402823E+38 Hashcode for Value2 = -8388609 TypeCode for Value2 = Single Is Value2 value is positive or negative infinity? = False
