[clisp-list] atanh(-2)?

[Raymond T. <ray...@er...>]

Clisp 2.35 (sorry, I haven't upgraded to something newer) says

(atanh -2) -> #c(-0.54930615 1.5707964)

But

(atanh #c(-2 1e-7)) -> #C(-0.54930615 -1.5707963)

The CLHS entry for atanh says atanh is continuous with Quadrant III
when the argument is on real axis and is less than -1.
