I'm concerned (mildly) about having the numbers converted from exact
to inexact. Inexact is what I have now with PERL. I'm interested in the
exact numbers and the final results of the programs. So, converting to
doubles probably won't happen. I'll look at doing my own put and get to
text columns.

Thanks for then answer Jay, and yes, I'm using your sqlite package.
