And, I'm fairly certain it was in 8.0, and I wouldn't be surprised if it were in 7.3 and earlier as well...;-)

Too late, there it is, in the 'Format models' section of the 8i docs.

Krishnan, this is how the to_char function works: it always leaves one extra leading space in the output to accommodate a potential minus sign when the format mask consists only of "9 "s (and potentially a decimal point alignment character). You can eliminate this by including the "fm " (fill-mode) element ( i.e., "fm99.99 "), or use the "tm " (i.e., "text minimum " ) element. In the "tm " case, you can only follow this element with a single "9 ", i.e., "tm9 ", in your format mask.
