This article describes the formula syntax and usage of the ATANH function in Microsoft Excel.
Description
Returns the inverse hyperbolic tangent of a number. Number must be between -1 and 1 (excluding -1 and 1). The inverse hyperbolic tangent is the value whose hyperbolic tangent is number, so ATANH(TANH(number)) equals number.
Syntax
ATANH(number)
The ATANH function syntax has the following arguments:
- Number Required. Any real number between 1 and -1.
Example
