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。
