I don't think that follows. The underlyng data will be measured in some metric unit of time like microsecond or nanosecond or something like that. So a base-10 representation will show exactly the precision that the underlying data has. On the other hand a floating point number will show a base-2 approximation that may in fact display with more digits than the underlying data representation has. -- greg -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
