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: 

Infinity
True
Infinity
True
-Infinity
True

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