Inverse Hyperbolic Tangent

Computes the hyperbolic argtangent of x. If x is not complex and is less than –1 or greater than 1, the result is NaN. The connector pane displays the default data types for this polymorphic function.

x can be a scalar number, array or cluster of numbers, array of clusters of numbers, and so on.
argtanh(x) is of the same numeric representation as x.
