Code:


« 1 1 300
  START 200 *
  NEXT

The maximum number of digits is limited by available memory, I think.

P.S.: This confirms Tugdual's post above, which I hadn't read yet. The HP-49G was the first HP calculator to be able to solve this, by the way.

I just typed 200 300 ^ on my 50g and got the same answer in under a second. Is there a reason that you used a loop with multiplication instead?

John

Yes, in 0.4193 s here. Then I was using the emulator in Debug4. I'd have to check the flags settings, but I'm sure it was in Exact Mode. Anyway, when I did 200 300 ^ I got an answer in scientific notation, not an overflow by what I can remember. I'll check it again later, as I'm away from the desktop computer now.

Gerson.

P.S.: I'd gotten 9.99999999999E499. I only didn't get an overflow error because of flag -21 setting. Upon checking the CAS MODES screen I noticed Numeric had been checked. D'oh, just unchecking it might've been easier!
