This debate turns out to be a tempest in a teapot. We have two formulae: e = lim(n->0) (1 + n)**(1/n) e = lim(n->inf) (1+(1/n))**n These are exactly the same. Note carefully the limits for each. (If you change vaiables to m = 1/n in either formula you get the other one.) Regards, Dave Scherer mailto:scherer@uiuc.edu
