A simple reverse polish notation calculator loosely based on my trusty HP-32SII that runs on iPhone, iPad, and Apple Watch!

If you are familiar with HP RPN calculators, the operation of this calculator should seem very straightforward - albeit simplified. It cant be programmed, and it doesnt handle binary, or hexadecimal numbers.

But, it has a clean, simple interface with large, easy to press buttons. It has all of the functions required for quick calculations when your iPhone is handier than your computer or calculator.

And, remember those cool calculator watches from the 1980s? Unfortunately, none of them were RPN. RPN Calc brings a reverse polish notation watch calculator to the Apple Watch!

In addition to the standard RPN Calculator app that runs on iPhone, iPad, and Apple Watch, RPN Calc includes a handy micro RPN Calc Today Extension available for convenient access to quick calculations from the pull down Today screen.

Décevant

Décevant sur deux points: - la pile nest que de deux nombres. Un peu juste quand même pour une RPN. - Ne conserve pas en mémoire le dernier nombre lorsquon quitte lapplication.

Inutilisable avec une localisation FR - Unusable with FR locale :-(

Impossible de rentrer un nombre de plus de 5 digits quand on utilise la localisation FR (espace comme séparateur des milliers, virgule comme séparateur décimal).

Passez votre chemin

Idem pour moi, les nombres a + de 4 chiffres ne fonctionnent pas : vous saisissez 3000 + ENTER et elle comprend 3.

RPN mit Handbremse

i. Kurze Anmerkung zu den vorhergehenden Rezensionen: die Stelleneingabe funktioniert hier über die Stellenposition E! Beispiel 250.000 --> 2,5E5 ii. der Taschenrechner ist brauchbar, allerdings noch weit von der normalen Funktionalität eines HP28S entfernt. Hätte mir ein mehrzeiliges Rechenfeld gewünscht.

it doesn´t work

can´t use numbers bigger than 4 digits

Ungeeignet

Praxisuntauglich da nur 4 Stellen

Nach Update schon besser, aber....

Habe bei meinen diversen HP-Rechnern (abgesehen vom 48er aufwärts) immer mit 4 Stackebenen gearbeitet, hier stehen nur 2 zur Verfügung, außerdem finde ich keine Möglichkeit x<>y (Tausch der beiden letzten Stackebenen).
