Re: [Swarm-Support] binary numbers

[Konrad_Richter]

Hi Marcello,
you could create a list [bitstring] for the agent, consisting of single
elements which take the values 0 or 1. The elements should have the
functions setVal and getVal (do not call them setValue and getValue, since
otherwise SWARM gets mixed up with some other functions it uses
internally). Then, the i-th value could be obtained by [[[agent
getBitstring] atOffset: i] getVal] - where the function getBitstring
returns the above mentioned list.
Hope, that helps,
greetings,
     Konrad

Sorry if this comes a bit off the topic:
Does anybody have a nice and clean way to handle binary numbers. I would
like to store some information about the agent as a binary number
(0100101), and have a call that returns exactly the digit I'd like.
Thus, if the agent has myBin=01001, the call [agent gimmeBin: 1] returns
0, [agent gimmeBin: 2] returns 1, [agent gimmeBin: 3] returns 0, and so
on. Of course, I could write gimmeBin as a sequence of if-then, but it
does not sound very neat.
Any hint?
thanks
