MathF.Atan2() Method in C# with Examples

The MathF.Atan2() method in C# returns the angle whose tangent is the quotient of two floating-point numbers.

Syntax

Following is the syntax −

public static float Atan2 (float val1, float val2);

Above, val1 is the x-coordinate of a point, whereas val2 is the y-coordinate.

Example

Let us now see an example to implement the MathF.Atan2() method −

using System;
public class Demo {
   public static void Main(){
      float val1 = 0.1f;
      float val2 = 0.9f;
      Console.WriteLine("Return value = "+(MathF.Atan2(val1,val2)));
   }
}

Output

This will produce the following output −

Return value = 0.1106572

Example

Let us now see another example to implement the MathF.Atan2() method −

using System;
public class Demo {
   public static void Main(){
      float val1 = 25f;
      float val2 = 25f;
      Console.WriteLine("Return value = "+(MathF.Atan2(val1,val2))* (180 / MathF.PI));
   }
}

Output

This will produce the following output −

Return value = 45
