Don't use FM or use FM9.0 Examples: 'SVRMGR' = Oracle8 Release 8.0.5.0.0 'test=#' = PostgreSQL 7.3b1 test=# select to_char(1, 'FM9.9'); to_char - 1.

No doubt, but it's what Oracle does (see tests posted to the lists by several people) and to_char exists to duplicate Oracle behavior. This is hardly the silliest aspect of to_char's definition, IMHO ... regards, tom lane ---(end of broadcast)--- TIP 3: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to [EMAIL PROTECTED] so that your message can get through to the mailing list cleanly

The FM modifier means to omit unnecessary trailing stuff. There is no reasonable business or scientific custom to leave a trailing point after a number. Or perhaps a more pragmatic question is, how would I print a number without the trailing point? -- Peter Eisentraut [EMAIL PROTECTED] ---(end of broadcast)--- TIP 3: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to [EMAIL PROTECTED] so that your message can get through to the mailing list cleanly
