For decades the limit on my calculator’s factorial was 69. That’s all my HP35, HP45, HP65, HP29C,HP38C, and H41C would do. Then the HP42 raised the bar to 253 factorial. Wow!
Now, thanks to this fantastic program by Joachim, a whopping 10,000 factorial (and more) is possible in a handheld. Unrounded, I checked! No more Stirling’s approximation. Check out π and e at 100,000 digits too!
I’m also a Numberphile fan. Now I have a calculator that will perform Y^^X. All I need is this calculator, a bowl of popcorn, and I’m ready for most of what Numberphile dishes out. I mean, there still is the likes of Graham’s number, but…
One thought, NextPrime would be a cool function.
Again, thank you for this program. If it were an RPN (reverse polish notation) calc I’d give it 5 stars. As it is I’d go 4.9999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999…

Thanks for your friendly review. I was thinking about reverse polish notation, but that might confuse other users. In a first step, version 2.2 now has copy&paste in the high precision mode. Parentheses would also be nice, they are on my todo list.
