=ATANH(number)
=ATANH(0.76159416)
This formula returns 1.00000001, which is the inverse hyperbolic tangent of 0.76159416.
=ATANH(-0.1)
The ATANH function also supports negative numbers. For example, this formula returns -0.100335348, which is the inverse hyperbolic tangent of -0.1.
The ATANH function calculates the inverse hyperbolic tangent of a real number between -1 and 1, excluding -1 and 1. It requires a number argument to return the result.
