Combine array elements

[RFeng]

I have a 1D array:

I want to combine the first 2 digits into a single digit to get:

Can't seem to find a way of doing this.

a(0) = a(0)*10+a(1)...

There are probably ways of simplifying this but as I don't know exactly what the use case is I have just shown you how you could do exactly what you have asked.

Hi R,

another approach:

Now the array can have more than 3 elements.

Still there might occur problems when those two elements will be "bundled" into a value larger than Max(I32)…

Your question is ambiguous because you don't even define the datatype of the array (numeric or string).

Assuming the simplest possibility, here's my solution. No need for any math:

Next time try to define the problem better. It would have helped tremendously if you would have attached a small VI containing typical data. Can you guarantee that all array elements contain single numeric digits? Can they be negative? If the first element is zero, do you want to display the leading zero in the result? Are hex digits allowed? So many unanswered questions!
