Article-I.D.: houxq.260 Posted: Thu Jan 27 17:38:00 1983 Received: Sun Jan 30 08:08:55 1983 I presume most of you are using Dedekind Cuts or Cauchy sequences for the definition of the real numbers. Can anyone out there prove .99...=1. (or even give a definition of .999...) using J.H. Conway's definition of numbers (J.H. Conway, "On Numbers and Games", Academic Press)?
