| It is possible to define a number so that it is stored in the database with 38 digits of precision. If I do this, how much space does a number really use if it doesn't actually use this degree of precision. Strangely, the internal storage for number (dba_tab_columns) suggests that the worst case usage for a number is 22 bytes, so how much space does it really take to store a number ?. | |
