# MathF.Asinh() Method in C# with Examples

MathF.Asinh(Single) Method is used to return the hyperbolic arc-sine of a floating point value.

Syntax: public static float Asinh (float x);
Here, it takes a standard floating point number.

Return Value: This method returns hyperbolic arc-sine of the given value. If the number is less than 1, it returns NaN.

Below are the programs to illustrate the use of the above-discussed method:

Example 1:

 `// C# program to demonstrate the ` `// MathF.Asinh(Single) Method ` `using` `System; ` ` `  `class` `GFG { ` ` `  `    ``// Main Method ` `    ``public` `static` `void` `Main() ` `    ``{ ` ` `  `        ``// Declaring and initializing value ` `        ``float` `value = 1.5f; ` ` `  `        ``// getting hyperbolic arc-cosine value ` `        ``// using Asinh() method ` `        ``float` `result = MathF.Asinh(value); ` ` `  `        ``// Display the value ` `        ``Console.WriteLine(``"Angle is {0}"``, result); ` `    ``} ` `} `

Output:

```Angle is 1.194763
```

Example 2:

 `// C# program to demonstrate the ` `// MathF.Asinh(Single) Method ` `using` `System; ` `using` `System.Globalization; ` ` `  `class` `GFG { ` ` `  `    ``// Main Method ` `    ``public` `static` `void` `Main() ` `    ``{ ` `        ``// calling get() method ` `        ``get``(0.19f); ` `        ``get``(Single.NaN); ` `        ``get``(Single.NegativeInfinity); ` `        ``get``(Single.PositiveInfinity); ` `    ``} ` ` `  `    ``// defining get() method ` `    ``public` `static` `void` `get``(``float` `value) ` `    ``{ ` ` `  `        ``// getting hyperbolic arc-cosine value ` `        ``// using Asinh() method ` `        ``float` `result = MathF.Asinh(value); ` ` `  `        ``// Display the value ` `        ``Console.WriteLine(``"Angle is {0}"``, result); ` `    ``} ` `} `

Output:

```Angle is 0.188875
Angle is NaN
Angle is -Infinity
Angle is Infinity
```
