Ugh, I guess I can't help NOW if you needed a quick finnish. =] (Just

finished a 1 week vacation.)



But here I go anyway:

AllPrevious is all the previous togather.

CurrentBit is the current bit (Doh! =).

Position is the bit position in the number.



In a 110010, it goes like this (use fixed lenght characters to see

chart):

          ^ We start here



AllPrevious + Current bit * 2 ^ Position = This

----------------------------------------

0           + 0           * 2 ^ 0        = 0

	This changes to AllPrevious and...

0           + 1           * 2 ^ 1        = 2

2           + 0           * 2 ^ 2        = 2

2           + 0           * 2 ^ 3        = 2

2           + 1           * 2 ^ 4        = 18

18          + 1           * 2 ^ 5        = 50
