C++ cmath atanh() function
Example
Return the inverse hyperbolic tangent of different numbers:
cout << atanh(0.78);
cout << atanh(0.5);
cout << atanh(1);
Definition and Usage
The atanh() function returns the inverse hyperbolic tangent of a number.
The atanh() function is defined in the <cmath> header file.
Syntax
One of the following:
atanh(double number);atanh(float number);Parameter Values
| Parameter | Description |
|---|---|
| number |
Required. A number to find the inverse hyperbolic tangent of, in the range -1 to 1. If the value is outside -1 to 1, it returns NaN (Not a Number). If the value is equal to -1 or 1 it returns -infinity or infinity. If the number is an integer type then it will be treated as a double.
