DESCRIPTION

22       These  functions  compute the complex arc hyperbolic tangent of z, with
23       branch cuts outside the interval [ −1, +1 ] along the real axis.
24

RETURN VALUES

26       These functions return the complex arc hyperbolic tangent value, in the
27       range  of  a  strip mathematically unbounded along the real axis and in
28       the interval [ −ipi/2, +ipi/2 ] along the imaginary axis.
