Rationalize[N[Pi,3], 0] 245850922/78256779 %//N 3.141592653589793 However, I suspect that N[Pi, 3] is not doing what you expect. You probably want something like Rationalize[Pi, 10^-3] 201/64 % // N 3.140625 or Rationalize[(x=10^-3)*Round[Pi/x]] 1571/500 %//N 3.142 Bob Hanlon In article <b5efg5$63h$1 at smc.vnet.net>, "Daniel Lidström" <daniel.lidstrom at _DELETE_home.se> wrote: << Subject: Re: Newbie question From: "Daniel Lidström" <daniel.lidstrom at _DELETE_home.se> To: mathgroup at smc.vnet.net Date: Fri, 21 Mar 2003 07:37:41 +0000 (UTC) Daniel Lidström wrote: > Hello, > > I couldn't find the FAQ.

I'm expecting a quotient. Thanks! /Daniel
