The C# Math Atanh() function returns inverse hyperbolic tangent of a value. The hyperbolic tangent of x is defined as:

Atanh

In special cases it returns the following:

  • If the argument is NaN, the method returns NaN.
  • If the absolute value of argument is greater than 1, the method returns NaN.

Syntax

public static double Atanh (double x);

Parameters

x Specify the value.

Return Value

Returns the hyperbolic tangent of a value.

Example:

In the below example, Atanh() function is used to find out the hyperbolic tangent of a value.

using System;

class MyProgram {
  static void Main(string[] args) {
   Console.WriteLine(Math.Atanh(0.1));
   Console.WriteLine(Math.Atanh(0.5));
   Console.WriteLine(Math.Atanh(2));
  }
}

The output of the above code will be:

0.10033534773107558
0.5493061443340548
NaN
