Table sizing question

The definition of a "NUMBER" says that it can occupy up to 21 bytes.

What are the acctual column sizes (number of bytes required) for something like

NUMBER(5)  	(a short integer range)
NUMBER(10) 	(an integer range)
NUMBER(14.7) 	(a float range)
NUMBER(22.15)   (a double range)

And what gave you that information?

Thanks
