ATANH

Applies to: Calculated column Calculated table Measure Visual calculation

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)  

Parameters

Term Definition
number Any real number between 1 and -1.

Return value

Returns the inverse hyperbolic tangent of a number.

Remarks

This function is not supported for use in DirectQuery mode when used in calculated columns or row-level security (RLS) rules.
