Re: A86: .db numbers


Binary is simple if you know powers of 2 off the top of your head. They
go up from right to left (which seems backward), and for every 1 in a
place, you add that corresponding number to a running sum, like this:

   2^ 7 6 5 4 3 2 1 0 <-- power of 2

      1
      2 6 3 1
      8 4 2 6 8 4 2 1

Example:
      0 0 1 0 1 1 0 1
    
          32 +8+4 + 1 = 45


It's really that simple. For an 8 digit number like above, the range
goes from 0 to 255, and negatives just work the other way, start with
all ones and add up the zeros, but you'll never use that in programming.
