ATANH function
This topic describes the formula syntax and usage of the ATANH function in the Data Quality Execute Formula transform.
Description
Returns the inverse hyperbolic tangent of a number. The 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 argument:
number Required. Any real number between 1 and -1.
Example
Data: RealNumber .076159416 and -0.1.
