R47 科学计算器
CHF 259.00
R47 是一款功能强大的基于 RPN 的可编程科学计算器，具备丰富的功能。其软件经过多年打磨，源于一支由工程师和数学家组成的团队——他们都是致力于计算器事业的爱好者——所构想的“梦想计算器”。
R47 由社区开发并由 SwissMicros 制造，其运行的固件在功能上与 C47 完全相同，这使得用户可以通过专用键盘贴膜，将 DM42n 转变为功能丰富的 RPN 计算器。
C47/R47固件最初是WP43项目的一个分支，而WP43项目本身又源自WP34S。这一系列中传承下来的核心组件是Mike Cowlishaw开发的decNumber库，用于精确的十进制运算。
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.
