I was showing a kid n 2 i k pi ==== -------- \ n > gamma(e r) / ==== k = 1 limit ------------------------ = - %gamma, 0<r<1, n -> oo n because it approximates a contour integral of Gamma(z)/z around 0, modulo the additional crudity of replacing pi sin(--) n pi ------- by --, i pi n ---- n e when he observed that the crudities somehow cancel: n = 1/r = 69 gives 126 digits! --rwg
