All I meant was that with a decimal exponent, the units could be dollars, and additions and subtractions of cents would be exact (assuming the mantissa has enough bits), with no worries about rounding. Which is the basis for this whole discussion. _______________________________________________ sqlite-users mailing list sqlite-users@mailinglists.sqlite.org http://mailinglists.sqlite.org/cgi-bin/mailman/listinfo/sqlite-users
