See http://www.hpmuseum.org/forum/thread-9566.html Thanks for the link. That was an interesting read. I was happily watching the blinkenlichten while the HP-25 emulator was calculating. So I tried to maximise the duration by using \(2^{33}=8,589,934,592\) but was slightly disappointed by the result: Only disk 5? Whereas I've expected 34. Turned out the given result was \(8,589,934,605\) which is off by \(13\). So I've entered the correct value manually. Those of you who wonder how an odd number could lead to disk 5 may notice that all the values are rounded to 10 digits. So that's a limitation of the program: \(0<n\leqslant10^{9}\). |
