In Oracle, if a column is declare as a NUMBER with no precison or scale, what is the default? The documentation I have doesn't seem to indicate it (or else I just can't find where it is defined).

A NUMBER datatype with no parameters is set to its maximum size.
Edit: Found another site that says if precision isn't specify, then 38 is used.

Okay, finally found it in the documentation. A column defined as a NUMBER is a FLOAT. Okay, that really makes sense, doesn't it.
