Calculatrice scientifique R47
La R47 est une puissante calculatrice scientifique programmable de type RPN dotée d'un ensemble complet de fonctionnalités. Son logiciel a été perfectionné au fil des ans, né de la vision d'une calculatrice de rêve développée par une équipe d'ingénieurs et de mathématiciens, tous passionnés de calculatrices.
Développée par la communauté et fabriquée par SwissMicros, la R47 utilise un micrologiciel fonctionnellement identique à celui de la C47, ce qui permet de transformer une DM42n en une calculatrice RPN riche en fonctionnalités à l'aide d'un cache-clavier dédié.
Le micrologiciel C47/R47 est issu d'un fork du projet WP43, lui-même dérivé du WP34S. Un composant essentiel de cette lignée est la bibliothèque decNumber de Mike Cowlishaw, qui permet un calcul décimal précis.
I understand that the R47 firmware is not written, distributed, or maintained by SwissMicros, and I agree that any support for the R47 firmware will be requested and handled by the R47 team via email to support@47calc.com.
The software (firmware) is currently in beta.
