R47 Calculatur da tastga scientific
Il R47 è in calculatur da tastgas scientific efficazi e programmabel che sa basa sin RPN e che ha ina vasta paletta da funcziuns. Sia software è vegnida raffinada durant blers onns ed è naschida ord la visiun d’in calculatur da siemis ch’è vegnì sviluppà d’in team dad inschigners e matematichers ch’èn tuts entusiasmads da calculaturs da tastga.
Il R47, sviluppà da la communitad e producì da SwissMicros, funcziuna cun ina rauba da firma ch’è funcziunalmain identica cun quella dal C47. Cun quella pon ins transfurmar in DM42n en in calculatur da tastga RPN cun bleras funcziuns, cun duvrar ina cuvrida speziala da tastatura.
La firma C47/R47 è naschida sco derivaziun dal project WP43 ch’ è puspè vegnì manà dal WP34S. Ina part centrala che ha pudì vegnir mantegnida en questa lingia da svilup è la biblioteca decNumber da Mike Cowlishaw per l’aritmetica decimala precisa.
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. Please see the documentation at https://47calc.com/
The software (firmware) is currently in beta.
