Sorry for not getting back to you, I was a little too focused (and
frustrated) on getting the guts of my lib to work.  

Here's a division example.  Actually, it errors out on the line where you
try to strip out the decimal before returning (BTW, 31600001 and 31600039
are both prime, and 998561264000039 is their product--you can actually test
this one with atoms) :

998561264000039 / 31600001 =
bigmath: 31600039
Kat: 3

998561264000039 / 31600039 =
bigmath: 31600001
Kat: 3

Subtraction (I haven't looked too closely at this, but the digits are mostly
right--there seems to be some periodicity to the discrepancies):

I didn't test against non-integers (most of the stuff I did uses integers).
