Isnt it defined for arbirtrary bases? (I think you wrote for base greater 1.)

So if you have the slog you have also the "sexp".

And I would compare this with what comes out from Daniel's solution for the hyperbolic case (there is then no problem with the convergence radius of the series).

and then take hyperbolic iterations .
