MathF.Acos() Method in C# with Examples

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

Syntax: public static float Acos (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.

Below programs will illustrate the use of the above-discussed method:

// C# program to demonstrate the
// MathF.Acos(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 Acos() method
        float result = MathF.Acos(value);
  
        // Display the value
        Console.WriteLine("Angle is {0}", result);
    }
}

    // 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 absolute angle value in float
        // using Acos() method
        float result = MathF.Acos(value);
  
        // Display the value
        Console.WriteLine("Acos({0}) will be {1}",
                                   value, result);
    }
}

Output:

Acos(0.19) will be 1.379634
Acos(NaN) will be NaN
Acos(-Infinity) will be NaN
Acos(Infinity) will be NaN
