One is to create a very small (as in spacing) one-dimensional grid of points, with which one can approximate derivatives and hence create a power series expansion at a given real point. From there, one can then find complex iterations.

So the way you explained to Sheldon - counting how often the exp winds around 0 and applying the corresponding branch logarithm - does not turn out to be useful?
