No.

Exactly as wrong as it was a year ago when this came up last:
<http://groups.google.com/group/sci.crypt/browse_frm/thread/4a5352739ef5519f>

There's a new twist this year in that you're simultaneously arguing that
computers are decimal. The two claims seem inconsistent: why should a
decimal computer have difficulty performing arithmetic on numbers larger
than 2147483647?

So you've concurrently got two belief systems each wrong in several ways
and which are mutually inconsistent. Is this some kind of attempt to
imitate Robert E. McElwaine?

So? My point is that if 2147483647 is special in some way that surely
indicates something's binary, not decimal. 8589934592 also has 10
digits, so why wouldn't that be allowed?

Perhaps, though if you mean "religious" to imply that there's no
relevant evidence, or that the views are equivalent, then I'd disagree.

On the other hand <http://xkcd.com/386/> surely applies.
