Returns the inverse hyperbolic tangent (arc tanh) of a Complex
, with branch cuts outside the interval [-1,1] on the real axis.
Complex
object. A newly constructed Complex
initialized to the inverse (arc) hyperbolic tangent of the argument. The imaginary part of the result is in the interval .
Specifically, if z = x+iy,
and atanh is odd.
