I think psycopg2 uses a painful way to get an integer coefficient via as_tuple(). What should really be added is either as_triple(), which would return (sign, coeff, exp) with an integer coefficient or make these attributes official: Decimal.sign Decimal.coeff Decimal.exp I have to think about implementing Decimal._int etc. Somehow I feel that doing so would send a wrong signal: People shouldn't assume that they'll get away with using private methods and attributes. Also, of course they'll keep using these private methods until they are finally deprecated, and *then* they'll have to change things. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue7652> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
