RE: space taken up by number data types

Yes, T.Kyte is still right :-)

Space is not reserved for NUMBER type, it is "variable length" column. Amount of space occupied depends on particular number, which is stored in the column.

I could have swarn I read that Precision with number data types effects how much space is reserved in the database. So number(38) and number(3) reserve different amounts of space.  

Here is a link from Tom Kyte in 1998 saying the opposite. Is what he says still true?
