Number Concatenation

We're glad you came by, but you might find what you're looking for elsewhere. TI-Basic Developer is not the site it once was. While its information on commands and other calculator features remains almost second-to-none, its forum, archives, and even hosting service, Wikidot, have been decaying for years. The calculator community would love to see what you're working on, or help you in your next coding adventure, but TI-Basic Developer is no longer the place to do it. Instead, you should head over to Cemetech (primarily American) or TI-Planet (primarily international). Both are active, well-established forums with their own archives, chatrooms, reference material, and abundant coding tools and resources. We'll see you there, we hope.

Number Concatenation

Trenly 25 Aug 2018 01:42

I need to concatenate all the numbers from a matrix. However, the current routine will not work for what I need it to:

N+M10^(1+int(log(N

The problem I have, is that when a 0 is attempted to be processed through this routine, It simply doesn't get concatenated. If N is 0, a Domain error is thrown. If M is 0, it simply returns N. Does anyone know of, or could create, an alternative routine that will concatenate including 0? Because of other restrictions, I cannot use strings.

I'm not sure that there is any incremental way to do it, since:

0123 = 123

You'd have to make sure there was an additional digit to "contain" the 0:

10123

meaning you'd have to do it in groups of two or more digits (but that doesn't even ensure success, since the 0 could lead a block of digits).

The solution to a complex problem is often a simple answer.

I'm not concerned about preceeding 0's. The current routine would concatenate 1,0,3 as 13 instead of 103

Edit:

Created a routine that will work for what I need it for

{0,2,0,4,5,6,0,8,9→L₁
0
For(E,1,dim(L₁)
Ans+L₁(E)*(₁₀^(dim(L₁)-E))
End
Ans
