Hello Bob,
DM41X f/w is 2.1
Lib#4 and HEPAX 4H plugged. That's all.

I could reproduce the bug at the moment as many times as I wanted, which allowed me to film the video...
... but could not repoduce afterwards!

I will try again to reproduce...

@walter @over_score About GMP : " GMP versions up to and including 6.1.2 did not use the Baillie-PSW primality test. In those older versions of GMP, this function performed reps Miller-Rabin tests. " So the older version of GMP where indeed limited to 3E24, like my algorithm... ... But, ve...

Merci Over_score,
Interesting... the Bailly-PSW test is my next RPN programming challenge

This test is hard-wired in the WP43S. Feel free to check PRIME?. Just FYI.

Up to what number is the test deterministic in WP43s?
or are you using random numbers as "base" to cover the full range of "integer"?

Hi all,
here is another weird multi-line editor bug caught on video (the video is not public, must have the following link)...

Hope it helps debugging...

Here is a DM42 program that checks if X register is a (big) prime number using the Miller-Rabin algorithm with a set of bases. The algorithm works up to 3 E 24 (well over 2 ^ 64).

I know Peet... But the chapter about CPU speed is different from the chapter on SLOW/FAST and there is no cross reference. So there could be some doubts... So something like : " SLOW corresponds to original 41C speed and is independent from CPU speed, FAST is roughly 50 times faster @24MHz CPU ...
