ATANH returns the inverse hyperbolic tangent of an argument and it is a Teradata extension to the ANSI SQL-99 standard.

Syntax:
SELECT ATANH(float)

ATANH(TANH(input)) = input



Note:
If the argument is not FLOAT, it is converted to a FLOAT value, based on implicit type conversion rules.
If the argument cannot be converted, an error is reported to the user.

Examples:
 SELECT ATANH(LN(0.5))

Result: -8.53988047997524E
