Reverse Polar Notation???? Message #1 Posted by Per Faltman on 11 Aug 2000, 7:21 a.m. Go to HP:s web site and click Buy HP/calculators. There you will see that 32SII (in the list, not where the pic is) uses the truly amazing Reverse Polar Notation...

Re: Reverse Polar Notation???? Message #2 Posted by Andrés C. Rodríguez on 11 Aug 2000, 7:56 a.m., in response to message #1 by Per Faltman It could be "Rectangular" Polish Notation too :-) Sadly, RPN is evolving from a "cool" idea into a "cold" place. That may be seen as "polar", indeed!

Re: Reverse Polar Notation???? Message #5 Posted by Carlos Tolossa on 14 Aug 2000, 1:42 a.m., in response to message #4 by Thibaut *RPN* IS NOT FOR EVERYONE, IT WILL BE ALIVE FOR A LONG TIME AND IT WILL BE USED BY SERIOUS, SOPHISTICATED, AND SMART FOLKS LIKE IT HAS BEEN. THE FACT IS, TI's CASIOS & OTHERS ARE CHEAP, HP's ARE NOT. HP's ARE FOR US 2% SPECIAL SOPHISTICATED SCHOLARS. HP’s ARE NOT FOR BIGGINERS… HP’s ARE NOT FOR THE BELOW AVERAGE INDIVIDUALS… LETS KEEP IT THAT WAY… MY FRIEND TOM DREWSKI ONCE WROTE…. “ HP’s DON’T MAKE SMARTER, HP’s MAKE YOU MORE SERIOUS” .

RPN... danger of extintion Message #6 Posted by Andrés C. Rodríguez on 14 Aug 2000, 7:52 a.m., in response to message #5 by Carlos Tolossa I surely think RPN is better than algebraic; the issue is that HP seems not to believe in RPN. All their new models are algebraic. In my opinion, the only RPN calculators available today are the HP 32S II and the HP 12C. The HP 48/49 family could be seen as RPN, I prefer to consider them in a separate RPL family... HP had shown little or no interest (at least, by now) on a HP 42S class machine; which is what many people here (at the MoHPC) would like to buy/have. And the interesting discussions at this Forum, about education market, textbooks and market size do not help to forecast a bright future for RPN. Sometimes RPN seems headed for extintion. Let us hope it will not happen. So, for people like the ones you describe (we), the problem will be: Where to buy an RPN calculator? (lest a 1980 used model at an electronic auction site) As Keynes said, "On the long term, we all will be dead". Then, RPN will no longer be a concern. A true pity.

Rodríguez "So, for people like the ones you describe (we), the problem will be: Where to buy an RPN calculator?" The answer may very well be in the form of an RPN calculator software package, that runs on our PDAs. I have a 48G at home as a desk calculator, but when I'm on the go I use Kalk (a freeware RPN calculator simulation) on a Palm IIIx PDA.

Re: RPN on PDAs Message #8 Posted by Andrés C. Rodríguez on 16 Aug 2000, 10:50 p.m., in response to message #7 by Michael Portuesi I do agree. In fact, some time ago (in this Forum) I advocated for this way to preserve RPN. For instance, I had a chance to use the BizCalc application on a Windows CE machine. It sort of emulates an HP 12C, with good performance and features.
