Single.IsInfinity() Method in C# with Example

In C#, Single.IsInfinity(Single) is a Single struct method. This method is used to check whether a specified floating-point value evaluates to either positive infinity or negative infinity or not. While performing some mathematical operations, it is possible to obtain a result that is either positive infinity or negative infinity. For Example: If any positive value is divided by zero, it results in positive infinity.

Syntax: public static bool IsInfinity (float f);

Parameter:
<emf: It is a single-precision floating-point number of type System.Single.

Return Type: This method return a boolean value True, if the specified value evaluates to either positive infinity or negative infinity, otherwise return False.

Example:

 // C# program to illustrate the // Single.IsInfinity(Single)  // Method using System;    class GFG {        // Main method     static public void Main()     {            // Dividing a Positive number by zero         // results in positive infinity.         float zero = 0.0f;         float value = 10.0f;         float result = value / zero;            // Printing result         Console.WriteLine(result);            // Check result using IsInfinity() Method         Console.WriteLine(Single.IsInfinity(result));            // Result of any operation that         // exceeds Single.MaxValue         // is Positive infintity         result = Single.MaxValue * 9.25f;            // Printing result         Console.WriteLine(result);            // Check result using IsInfinity() Method         Console.WriteLine(Single.IsInfinity(result));            // Result of any operation that         // is less than Single.MinValue         // is Negative infintity         result = Single.MinValue * 9.565f;            // Printing result         Console.WriteLine(result);            // Check result using IsInfinity() Method         Console.WriteLine(Single.IsInfinity(result));     } }

Output:

Infinity
True
Infinity
True
-Infinity
True

Note: Floating-point operations return PositiveInfinity or NegativeInfinity to signal an overflow condition.
