# 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.
