I'm struggling how to do this calculation in Max:

My program will return a "3", meaning that the 3rd bit in an 8-bit number is "on" (100, or 4) . A "4" means the 4th bit is "on" (1000, or 8), and so on. But I'm having trouble converting the initial number that signals which bit is on (3 or 4 in the above examples) to its binary or decimal version (again, 100/4 or 1000/8 in the above examples). Any thoughts?

PDELGES, that is perfect! One more question: do you know of a way to make it so that the binary number being output is always being expressed as an 8-bit number (e.g. "100" = "00000100")

 a number as a binary, but if you need a message that looks like a binary, then you need some conversion (

may help). Then you can do some zero padding with [combine].

Sorry, I don't have Max at hand and can't send you an example.

Be carefull, the patch I sent displays a number as a binary, but if you need a message that looks like a binary, then you need some conversion (this topic may help). Then you can do some zero padding with [combine].

i might have done that somewhere but i am not sure.

I know I know, but I didn't like the idea of having 2 ^ -1 for 0 as input AND I wanted to keep some "bitwise operations" as asked in this thread's subject.

By the way, with modern systems you can go up to 62 without trouble ;-) (but I still enjoy- using Max4 and Max5 too !)

i was about to ask: so it happens with 63 @ 64, too. :)

I'm afraid there will be need for 128bits processors very soon! And Max16.

Yes Roman, it does happen.

Trouble with bitwise operations..
