MathF.Acos() Method in C# with Examples
The MathF.Acos() method in C# is used to return the angle whose cosine is given as a float value argument.
Syntax
Following is the syntax −
public static float Acos (float val);
Above, Val is the floating-point number.
Example
Let us now see an example to implement the MathF.Acos() method −
using System; public class Demo { public static void Main(){ float val1 = 0.1f; float val2 = 0.9f; Console.WriteLine("Angle (val1) = "+(MathF.Acos(val1))); Console.WriteLine("Angle (val2) = "+(MathF.Acos(val2))); } }
Output
This will produce the following output −
Angle (val1) = 1.470629 Angle (val2) = 0.4510269
Example
Let us now see another example to implement the MathF.Acos() method −
using System; public class Demo { public static void Main(){ float val1 = 2.5f; float val2 = 5.0f; Console.WriteLine("Angle (val1) = "+(MathF.Acos(val1))); Console.WriteLine("Angle (val2) = "+(MathF.Acos(val2))); } }
Output
This will produce the following output −
Angle (val1) = NaN Angle (val2) = NaN
