I know this might be simple but I need to know how to split a 12 digit number into 12 seperate integers. I'm going to use a upc scanner to generate a 12 digit number. I need to pipe each digit through my program to create an algorithmic poem. I hope that this is possible.

this-is-either-basic-or-impossible

there's probably a smarter way to do this, but this task is easy with

a bit of math.... take that 12 digits, divide by 10000000000, cut of

the decimals, and blam, there's the 12th digit, which I'll call X.

then take the 12 digit number, subtract (100,000,000,000 * X), then

To do it in Max you would need [spell] and [itoa]

you can also do this pretty easily with java script...

        outlet(0, str.charAt(i));

	for(i = 0; i < 12; i++)
		outlet(0, str.charAt(i));

I'm sure you'll get plenty of answers, but here's a word of warning: 

Max will strip any leading zeroes from your number (at least, if you 

present it to Max in the lexical form of an integer). I ran into this 

issue using RFID tags (which are strings of digits, not integer 

values), so I ended up prefixing the digit strings with a symbol ("_" 

The downsize of *this*, of course, is that it will pollute Max's 

symbol hashtable. But the alternatives (such as presenting lists of 

digits from the device) might be too complicated to contemplate.

If leading zeroes are not significant to you, then this issue is moot.

I think that you will run into number representation issues with a number that large. 2147483647 is as big as you can represent in 32 bits, higher than that and a 32 bit representation will wrap negative.

Does the scanner really bake a 12 digit number, or is there some way it can chunk it up into smaller pieces.

The main problem will be to deal with that as a number, as 12 digits 

exeed the 32-bit integer space in Max. But if you do it as a string, 

there is no problem, atoi, and some filtering will give what you need...

This problem is not so simple as it seems - if you try and write a twelve digit number like 999999999999 or even 100000000000 to a message box or number box you'll get in trouble because they require more than 32 bits to represent them. Max at the moment is limited to 32 bits So you need to treat the number as a symbol, split up the symbol and then convert back to int's at the end.

Ha ha Stefan you beat me by 4 mins (i had to take a call) - Stephan's is a better solution really, it's a bit more economical.

LISP is pretty good at this stuff, especially the bignum 

capabilities. To separate a string like "18162839718528375" you 

could use these functions (apologies for my bad prog-form lisp; I'm 

     (setq str (make-string-input-stream (string sym)))

     (cond ((null (setq ch (read-char st nil))) (return nil))

     (t (return (cons (objectify ch) (collectem st))) )

     (read (make-string-input-stream (string c)))

but (as others have noted) you'll have difficulties getting this kind

ok one last shot as i was feeling inadiquate after my first attempt - now only 3 objects....

But none of the solutions so far have really addressed the problem of how the original poster can get his 12 digit number into Max as text in the first place. I would like to hear from the original poster again, to better understand how the scanner delivers the numbers.
