The ATANH function returns the hyperbolic arc tangent of a number, in radians. The ATANH and TANH functions are inverse operations.
The data type of the result is double-precision floating point. If the argument can be null, the result can be null; if the argument is null, the result is the null value.
SELECT ATANH(:HATAN) FROM SYSIBM.SYSDUMMY1Returns the approximate value 1.50.
