R47 Calculator Introduction (Updated)

The R47 is a powerful, RPN-based programmable scientific calculator with an extensive feature set. Its software has been refined over many years, born from the vision of a dream calculator developed by a team of engineers and mathematicians, all dedicated calculator enthusiasts. The hardware is by SwissMicros, the firmware is open source and provided by the developers. The C47/R47 firmware originated as a fork of the WP43 project, itself derived from the WP34S. A core component carried through this lineage is the decNumber library by Mike Cowlishaw, also used in GCC for precise decimal arithmetic. Inspired by the HP‑41C and HP‑42S, the R47 has a keypad featuring two shift keys, preserving a familiar feel while being entirely new in execution. For a quick demo of the handling of 1000 digit integers, see this short:    • R47 Calculator (thousand digit integers)   (Description derived from swissmicros.com/product/model-r47) (Video by Barry Mead, as posted at forum.swissmicros.com/viewtopic.php?t=4605, reuploaded with permission) A previous version of this introduction can be found here:    • R47 Calculator Introduction
