function artanh( |
x: float |
):float; |
artanhreturns the inverse hyperbolic tangent of its argument x, where xshould lie in the interval [-1,1], borders included. The arctanhvariant of this function is supplied for Delphi compatibility.
In case xis not in the interval [-1,1], an EInvalidArgumentexception is raised.
