Is there any way, in a pure TI basic program, to convert a real number into a string?

On the other hand, I find this method slow. There's an even better method. See this post:

Here's a Zeda Quote:
Depending on what form the number will be in, you could definitely make some faster codes. If it is only ever a positive integer, for example, you could do something like this:
;C is the number to convert
"0→Str1
Repeat not(C
sub("0123456789",1+10fPart(.1C),1)+Str1→Str1
iPart(.1C→C
End
sub(Str1,1,length(Str1)-1

If you want to do it with Hybrid BASIC, there's an even faster method to convert reals to strings:

My goal is to do it with no dependencies. And, yes I did do a google search and turned up the LinReg version, but it was slow so I thought I'd ask.
Will Roguebantha's pasted routine work with all real numbers? Zero, positive, and negative? Integers and fractions? Or will I need to fix it up a bit?

Please engage your brain.
Oh. I didn't even see that...
Edit: realized I only need positive anyway. But I do need decimal support.

With a bit of simple BASIC string manipulation you should be able to expand it to support decimals. Edit: realized I only need positive anyway. But I do need decimal support.
I'll work on it. In the meantime, I'll release it with the LinReg method. Now...to get my computer back from the Apple Store...
If you tried the linreg solution and it was too slow why didn't you say so in the first post? Then I wouldn't have bothered to take the time to post it since we would have already known you tried it.

Sorry. I had literally 30 seconds to make the post.
Edit: I figured it out... in psuedocode.
1-->dim(L1)
iPart(number) --> E
If int(number) /= number:Then
fPart(number) --> F
Repeat int(F)=F
Fx10-->F
End
dim(L1) + 1 --> dim(L1)
F-->L1(2)
End
For (A, 1, dim(L1))
//do the code that only works for positive integers
If dim(L1)-A > 0:Then
String + "." --> String
End
End
