MathF.Atanh() Method in C# with Examples

MathF.Atanh(Single) Method is used to return the hyperbolic arc-tangent of a floating point value.

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

Return Value: This method returns hyperbolic arc-tangent of the given value. If the number is less than 1, it returns NaN.

Below are the programs to illustrate the use of the above-discussed method:

Example 1:

// C# program to demonstrate the
// MathF.Atanh(Single) Method
using System;

class GFG {

    // Main Method
    public static void Main()
    {

        // Declaring and initializing value
        float value = 1.7f;

        // getting hyperbolic arc-tangent value
        // using Atanh() method
        float result = MathF.Atanh(value);

        // Display the value
        Console.WriteLine("Angle is {0}", result);
    }
}

Output:

Angle is NaN

Example 2:

// C# program to demonstrate the
// MathF.Atanh(Single) Method
using System;
using System.Globalization;

class GFG {

    // Main Method
    public static void Main()
    {
        // calling get() method
        get(0.25f);
        get(Single.NaN);
        get(Single.NegativeInfinity);
        get(Single.PositiveInfinity);
    }

    // defining get() method
    public static void get(float value)
    {

        // getting hyperbolic arc-tangent value
        // using Atanh() method
        float result = MathF.Atanh(value);

        // Display the value
        Console.WriteLine("Angle is {0}", result);
    }
}

Output:

Angle is 0.2554128
Angle is NaN
Angle is NaN
Angle is NaN
