That's fine by me. ;-)
This seems to be one of the improvements of the HP67 compared to its predecessor.

Me neither. But good to know.
Now I think I wll have to try the Panamatic HP65 emulator.

Edit: The mentioned emulator should run the original microcode and thus behave like the real thing. According to my results the interval around zero where e^x is rounded to 1 is –6,1 E–11 < x < +5 E–10.
