Hello Valentin and Albert,

I will. First I have to read a little more of the HP39Gii manual... It has it's own programming langauge, a bit of a mix of everyting. Some BASIC, some keystroke programming and every line has to be terminated with a semicolon just like in C.

Quote:I don't understand. The key to this mini-challenge is that all four means mentioned ... are cases of a Generalized Mean ... is defined as:

So this is the core of the stupid question I was too afraid to ask ;-) Like Albert I had never heard of this before. Instead I falsely assumed that your April fool's challenge was based on arbitrarily assigning discrete indices to different ways of calculating means and then somehow interpolating between them.

I asked Wikipedia about it and found out that in Germany it is actually called the "Hölder-Mittel" (https://de.wikipedia.org/wiki/H%C3%B6lder-Mittel) of which I had never heard before either. A strange kind of April First sidenote is that it is also known as "Potenzmittel". Now this is a German word which also has a completely different meaning that one usually associates with male-specific medication, the most prominent brand name being "Viagra".

But I will go back to my 39Gii (*) and see if I can administer the "Potenzmittel" somehow into it's memory :-)

Regards
Max

(*) In case anyone wants one: There is a guy in the UK who currently sells off these calculators for 10 GPB a piece + shipping on eBay. This is where I got mine from. They come from a girs-only boarding school on the outskirts of London and don't seem to have seen much usage - if any at all. Decent value for money if one does not want or need RPN/RPL.
