I have the same result as Ingolf, with a 3-yr-old AMD 3200+ processor, WinXP, and Mathematica v6. $MaxNumber 1.920224672692357*10^646456887 Bobby On Wed, 05 Sep 2007 01:55:05 -0500, Ingolf Dahl <ingolf.dahl at telia.com> wrote: > Strange, on my 32 bit PC:s (running Windows XP and Mathematica 5.2 and > 6.0), > $MaxNumber is > 1.9202246726923565854204690606`15.954589770191005*^646456887 > > I use (single) Intel Pentium 4 processors.
