You cannot do it using the standard reals because it would require the existence in the standard real number system of e an infinitesimal nonzero lambda smaller than any positive standard real but itself positive, and an infinite cardinality, card(N), of the infinite set of naturals such that lambda * card(N) = 1.
Which cannot occur within the essentially unique (up to isomorphism of complete ordered Archimedian fields) standard real number system.
