[SOLVED + CAVEAT] [libreoffice-users] rounding problem with Base

A bit weird. If I could give a suggestion I'd make the default format for numbers in queries follow the same schema as in postgresql (and most DB I know). NUMERIC(A, N) * NUMERIC(B, M) - NUMERIC(A + B, N + M) and FLOAT/DOUBLE all significant digits.

To summarize it for posterity: I wasn't able to appreciate if any change I was doing to the type used (NUMERIC(N, M) or FLOAT or DOUBLE) in SQL operations was effective since all I could get out from the DB was 2 decimals either in simple format (1234567898,31) or scientific format (6,23E+015). Not being able to see any change tricked me into thinking that no matter what type I was using there was no effect on precision since I'm used to something like: test=# select 1.01::numeric(4,2)*2.02::numeric(4,2); ?column? -- 2.0402 (1 row) The problem was just a problem of output format that can be set once you run the query, and in the result window right click on the column name and change the format. Thanks for the moral support anyway. -- Ivan Sergio Borgonovo http://www.webthatworks.it -- To unsubscribe e-mail to: users+unsubscr...@global.libreoffice.org Problems? http://www.libreoffice.org/get-help/mailing-lists/how-to-unsubscribe/ Posting guidelines + more: http://wiki.documentfoundation.org/Netiquette List archive: http://listarchives.libreoffice.org/global/users/ All messages sent to this list will be publicly archived and cannot be deleted
