# Excel ATANH Function

This post will guide you how to use Excel ATANH function with syntax and examples in Microsoft excel.

### Description

The Excel ATANH function returns the inverse hyperbolic tangent of a given number. So you can use the ATANH function to calculate the inverse hyperbolic tangent for a number. The returned result is a numeric value.

The ATANH function is a build-in function in Microsoft Excel and it is categorized as a Math and Trigonometry Function.

The ATANH function is available in Excel 2016, Excel 2013, Excel 2010, Excel 2007, Excel 2003, Excel XP, Excel 2000, Excel 2011 for Mac.

### Syntax

The syntax of the ATANH function is as below:

`= ATANH (number)`

Where the ATANH function arguments is:

• number -This is a required argument. A real number between 1 and -1, but it should exclude the values of -1 and 1.

Note:

• If the number argument is greater than or equal to 1, the ATANH function will return #NUM! Error. If the number argument is less than or equal to -1, the ATANH function will return #NUM! Error.
• If the supplied number is not a numeric value, the ATANH function will get the #VALUE！ Error。
