separate integer digits to array

[mabaig]

Greetings all

Can someone tell me how do i separate integer in to separate digits in an array.

Eg: 4409

array elements: 44

                            9

Thanks and Regards

Aren't these four digits: 4 4 0 9 ?

[mabaig]

Hi

it is but since those are integers 09 will be 9

Thanks and regards

So you don't' want to separate digits.  You want to separate PAIRS of digits?

This is how I would do it. If you change the 2 to a different number it would give how ever many digits.

[RavensFan]

I would use Quotient and Remainder and divide by 100.

You are still not giving us sufficient information.

• Is the input a string with four character or a numeric?
• If it is a numeric, what is the datatype?
• Are negative inputs allowed, and if so, how should they be handled?
• Is it always four digits or can it be variable length?
• What should be the output datatype?

Typically it is much easier to solve a problem if you would attach a very simple VI that contains the actual data and desired output.

Here's a slightly more scalable version of the above that can deal with any number of digits supported and will output all decimal digit pairs of the positive input integer.

All of the previous methods have been a simple way to accomplish this problem, so I decided to make a hard way to accomplish this problem. I also assumed that the task is to get each single digit, not pairs of digits; if you want pairs of digits, that is left as an exercise to the reader.

I like Bert's solution, but the latent Mathematician in me calls out for a Recursive solution (which, of course, is very simple to write in LabVIEW).  I made the input a U32, thereby getting rid of a possible ambiguity if you put in a negative integer.  I also assumed that the number 4409 (using our usual "digit-place representation" of numbers, has the digits "4", "4", "0", and "9".  Here is the (almost trivial) VI, showing the Recursive call -- this version puts the digits of 4409 in an Array starting with the Least Significant Digit (i.e. "9") -- reversing the order of building the Array will give the digits in the reverse order.  Enjoy!
