Is that off scope consideration for this thread?
I know that the prime is blazing fast but the speed is so impressive that I wonder if the calculator is actually performing a loop?

For reference:
The TI-36X Pro arrived at the answer of 0.693097183 in 5:45 minutes.
The Casio fx-115ES Plus took just over 11 minutes to arrived at the answer of 0.6930971831.
It's a good thing these models are solar poweredSmile
Not bad for $20 machines.

The Casio ClassPad 330 takes 57.5 seconds to reach 0.6930971831
