rcal - a "rolling" calculator

Copyright © 2018-2024 Mateusz Viste

rcal is an interactive calculator for DOS, that loosely mimics the behavior of "roller printing" calculators. It supports huge numbers, floating point and has extremely low hardware requirements. Read more: rcal.txt

rcal is published under the terms of the MIT license, and relies on the excellent APM math library (1988) by Lloyd Zusman.
