N[50000,2] should represent something between, say, 49500 and 50500, both of which are positive. If it means something other than that, please enlighten us!! Meanwhile, perhaps we can use Interval to interpret it: Interval[N[50000, 2]]//InputForm Interval[ {49488.`1.9955298983230858, 50512.`2.0044245602121236}] Interval@N[50000,2]>0 True So I don't see how this makes sense: N[50000,2]>0 False Bobby On Sun, 20 Feb 2005 10:53:16 +0100, Andrzej Kozlowski <akoz at mimuw.edu.pl> wrote: > Then surely you must have filed a bug report as it would be > irresponsible not to! > > Andrzej Kozlowski > > On 20 Feb 2005, at 06:10, DrBob wrote: > >> This behavior will find defenders, I'm sure, but it certainly looks >> like a bug to ME. >> >> Bobby >> >> On Sat, 19 Feb 2005 02:31:49 -0500 (EST), Gehrmann, James E >> <jgehrman at saclink.csus.edu> wrote: >> >>> I'm running Mathematica v. 5.1 under WinXP and had the following >>> interaction with Mathematica: >>> 5>0 >>> >>> True >>> >>> 5.>0 >>> >>> True >>> >>> N[5]>0 >>> >>> True >>> >>> N[5,3]>0 >>> >>> True >>> >>> N[5,2]>0 >>> >>> False >>> >>> N[50000,2]>0 >>> >>> False >>> >>> Are the last two results a bug or am I not understanding the N >>> function? >>> >>> Thanks for you help. >>> >>> >>> >>> >> >> >> >> -- >> DrBob at bigfoot.com >> www.eclecticdreams.net >> >> > > > > -- DrBob at bigfoot.com www.eclecticdreams.net
