Jamin,

I had a situation a while back where at certain settings in the prefs for
the number of digit places, that you would get  weird results (off by one).
This was a thread on AOL for a while.

After finally convincing others that it was real,(Al Staffieri could
duplicate the problem, praise him) Andy said it would be fixed later. It
only occurs at certain settings of the floating arithmetic prefs, maybe the
8-6-8 setting.
Not sure anymore. But I would get that same 1 off results when I used
parentheses.

I would get 1-(10)=-8 at times. ;)
