| EE Pros: Is RPN still relevant? |

Vo=Vin(1-e-t/RC) This is a nice formula for sorting out calculators. It's not like we don't use it from time to time. |

Any combo of 's or s'? --- End quote --- Yeah, it's a weird one. The ending is modified, rather than appending a suffix, in order to create the plural inflection. Change the 'is' to an 'es'. Singular: parenthesis Plural: parentheses |

Change the 'is' to an 'es'. --- End quote --- It comes from (late) Latin, 3rd declension. The Nominative case ends (often) in -is for the singular and -es for the plural. Many other names in the technical field come from Latin (and Greek, either directly or, once again, through Latin), e.g.: analysis, pl. analyses. IT (In Topic): I just got an HP 35s. Yes, I know it has bugs. Yes, I know it's not really exactly as the old HPs. Still, I feel at home using it. |

With regard to the "physical calculator", that rather depends on what you regard as 'physical' these days with smartphones etc. Personally I use Neocal on an old but perfectly serviceable Palm TX, perfectly physical to me. Anyway, the point I want to make is that these devices can normally allow you to view the entire RPN stack, not just the X register. This is invaluable in both ease of learning and reducing errors in operation. There are very few 'physical' RPN calculators (especially the 'classics') that display more than one line. --- End quote --- I think it's obvious from context that he means an actual calculator, not an app running on something else. I recently acquired an HP-15C to go with my HP-16C, and I love it. It's not the fastest calculator out there, but it's damn powerful. And user satisfaction? Through the roof. :-+ |

The thread is about whether RPN is still relevant though, and the point I was (clearly) making was about physical limitations of their displays and the benefits of having the whole stack visible. Surely we're talking about the advantages of RPN, not (now relatively rare) calculator model 'fandom' (I had a 16C from new but don't miss it compared to what I use now). |
