ATANH(z)

This function gives the Inverse Hyperbolic Tangent of a number.
Here 'z' is any number between -1 and 1. ie $-1<z<1$
Inverse Hyperbolic Tangent of a number is defined by $Atanh(z)={\frac {1}{2}}\log _{e}({\frac {1+z}{1-z}})$
TANH(-z)=-TANH(z). Also ATANH(TANH(z))=z
ATANH(1)=Infinty

ATANH(z)
