Well...  I think number bases are kind of off topic for Lojban, and I
wouldn't like to see a big flame war on this topic overload my mailbox.

Having written a libc instance including printf and scanf (with a
proprietary extension for generalized radix), plus some pretty bizarre
stuff for S/360 (yes, that ancient) involving megadigits and decimal
arithmetic, I can say from experience that for the computer the choice of
radix is not a big deal.  For greatest human convenience, maximizing the
number of integral divisors of the radix is important, and duodecimal
stands out in that property.

In a piece of fiction my characters had seven tentacles and used a heptal
number system.  I really think this is the most important consideration in
picking the radix: the number of appendages on the user.  On the boss user,
and *we* are the boss of the computers.

Drifting off topic again: in heptal or duodecimal or decimal or hex or
whatever, how do you write the radix?  10, of course.  The solution I used
in the proprietary radix extension was to have the user specify radix-1,
that is, 6 -> heptal, f -> hex, 9 -> decimal, etc.
