Storage Question

Hi,

Hope this is the appropriate NG for this...

How does Oracle store number columns internally? For example, if a table has a column of NUMBER(20), does each number require 20 bytes (one byte per decimal digit), or is it stored as an internal binary representation (8 bytes?). Are there optimum NUMBER sizes that correspond to native machine word sizes (16 bit, 32 bit etc.)
