by RPN do you mean "Reverse Polish notation"?

At the moment Smart Math Calculator does not support Reverse Polish notation but there is popular demand for this we will add it to a future version. Personally I don't think this is a popular notation but if anyone has opinions about it please feel free to post them here.

RPN

Hi all.
RPN is no more widely used, but because I am 52 years old I clearly remember its use in the old, and very good, HP pocket calculators. In those times their main practical advantage with respect to common algebraic calculators, like Texas for instance, was in the easiness of correcting the last entry of a long calculation in case of any error. Speed and memory use in programmable calculators was better too. Nowadays on a PC based calculator both these aspects are probably no more really important.
That's all by a rational point of view, but I should like to have support for RPN, because for some calculations it is a more efficient way to think about what you have to compute. It would give some more appeal to Calculator. Of course you have to evaluate how much effort it requires and if it is worth to from Runiter's point of view.
Best regards
Enrico

Indeed it's something I can add but only if there's popular demand for it. Perhaps I will add it as an option next time I post a voting questionnaire for deciding next version features.

RPN - HP calculators

Post  navyfalcon on Tue Aug 17, 2010 2:15 am

RPN is used on HP calculators. They are still popular with Math, Physics, and Engineering Majors in the Universities. Now they use HP 48, 49, and 50 model calculators.
I don't think it will be popular for this calculator, as the HP is a programmable calculator and its main programs are for advanced math (such as analytics).
