I guess that's why Linda asked: Should 0.33333333 really be 1r3 ? Raul showed that it is.

If a number starts out inexact, it will stay inexact forever, even if you later apply x: (though then it will be quite exactly inexact :). Thus, to get 1r3 you must say 1r3. If you say 0.333 you'll get 0.333 . That's not 1r3 and never will be. -Dan ----- Original Message --------------- Subject: [Jbeta] Odd Pattern of Rationals From: "Linda Alvord" <[email protected]> Date: Wed, 12 Nov 2014 23:10:14 -0500 To: <[email protected]> Should 0.33333333 really be 1r3 ? x: 0.333333 333333r1000000 x: 0.3333333 3333333r10000000 x: 0.33333333 1r3 x: 0.333333333 166666671r500000014 x: 0.3333333333 3333333057r9999999173 Linda ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
