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
