Saving space by using nulls?

Say that I have 2 identical tables with the only difference that one table
allows nulls on all of its *numeric* columns and the other one does not.
Now say that I add the same amount of rows to both tables with the only
difference that on the table that does not allow nulls in its numeric
columns I insert numeric values while in the one that does allow nulls I
insert <<Null>> value.
Will both tables use the same storage space or would the table that allows
nulls use less space because I am insetting Null values on it?
Thanks
Same. As of 7.0, space requirement for fixed length column is the same regardless if a column of a
row has null or an actual value.
