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

MathF.Atan(Single) Method is used to return the angle whose tangent is given as a single value argument. If the argument is NaN, then the result will be NaN.

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

Return Value: This method returns an angle Θ, measured in radians, its type is System.Single and value will be less than Single.MaxValue.

Example 1:

 `// C# program to demonstrate the ` `// MathF.Atan(Single)  Method ` `using` `System; ` ` `  `class` `GFG { ` ` `  `    ``// Main Method ` `    ``public` `static` `void` `Main() ` `    ``{ ` ` `  `        ``// Declaring and initializing value ` `        ``float` `value = 0.5f; ` ` `  `        ``// getting absolute angle value in float ` `        ``// using Atan() method ` `        ``float` `round = MathF.Atan(value); ` ` `  `        ``// Display the value ` `        ``Console.WriteLine(``"Angle is {0}"``, round); ` `    ``} ` `} `

Output:

```Angle is 0.4636476
```

Example 2:

 `// C# program to demonstrate the ` `// MathF.Atan(Single) Method ` `using` `System; ` `using` `System.Globalization; ` ` `  `class` `GFG { ` ` `  `    ``// Main Method ` `    ``public` `static` `void` `Main() ` `    ``{ ` `        ``// calling get() method ` `        ``Console.WriteLine(``"Angle(in radian) are respectively"``); ` `        ``get``(0.19f); ` `        ``get``(0.23f); ` `        ``get``(0.45f); ` `        ``get``(0.67f); ` `    ``} ` ` `  `    ``// defining get() method ` `    ``public` `static` `void` `get``(``float` `value) ` `    ``{ ` ` `  `        ``// getting absolute angle value in float ` `        ``// using Atan() method ` `        ``float` `round = MathF.Atan(value); ` ` `  `        ``// Display the value ` `        ``Console.WriteLine(``"Angle of Atan({0}) will be {1}"``, ` `                                             ``value, round); ` `    ``} ` `} `

Output:

```Angle(in radian) are respectively
Angle of Atan(0.19) will be 0.1877619
Angle of Atan(0.23) will be 0.2260684
Angle of Atan(0.45) will be 0.4228539
Angle of Atan(0.67) will be 0.5903068
```
