Hi guys,
It's been a while since I've been on Omnimaga, but now that I have some time, I would like to get back to my program.

Basically, I gave up on it because after I wrote the code for displaying numbers that don't completely fit on the screen, I found that it stopped giving the correct answer at some random number. For example, it can tell me the first and last digits of 2¹⁵⁵, but it gives an odd number for 2²¹⁰, which is clearly not correct. I know that the Nspire isn't running out of RAM, because it's consistently able to make arrays of 18,000,000 chars. I don't know what the problem is, because I don't know why the program would just stop working after some arbitrary number.

Any ideas?

Yeah, I've noticed that my program always outputs numbers with a lot of 2809's and 2810's if it fails. I'll check my power function, it probably has some memory allocation bugs...
