I have just recently discovered an another and extremely rare BUG in HP 35. That bug was very early fixed by HP company and therefore even vast majority of Red Dots don't have that bug already.
It might be in other HP 35 too, provided that that buggy ROM would be accidentaly placed into some HP 35. You can test your HP 35s by this sequence:

1 eex chs 10 ln

and if you'd be a lucky owner of such HP 35 :-) then you'd receive an erroneous answer differing from the correct answer by hunderts of percents!

I get -23.02585093 the same output from a 41C... I guess mine doesn't have this bug.

What do you get instead?
