Source position: math.pp line 259
function arcosh( |
x: float |
):float; |
Arcoshreturns the inverse hyperbolic cosine of its argument x. The argument xshould be larger than 1. The arccoshvariant of this function is supplied for Delphi compatibility.
If the argument xis not in the allowed range, an EInvalidArgumentexception is raised.
