Full Screen RPN Calculator for Mac
Full Screen RPN Calculator is a lightweight and self-explanatory application for Mac OS X that attempts to emulate the functions of an HP RPN calculator on your desktop. On top of that, it comes with support for OS X Lion’s full-screen feature.
The calculator is not actually based on the HP series of calculators, because it includes only a limited number of functions: CHS, CLa, CLx, x-y, as well as the 4 common operations: addition, subtraction, multiplication and division.
Furthermore, Full Screen RPN Calculator’s main window can be easily resized to adjust to your vision, and you can also use it in full-screen mode. The latter feature, as mentioned, can only be activated in Mac OS X 10.7 or later.
Another handy function of the application is the ability remember memory registers after you quit and reopen Full Screen RPN Calculator. This helps save a little time by not entering the same numbers and functions in future uses.
Taking every aspect into consideration, Full Screen RPN Calculator is definitely not a scientific desktop calculator, not to mention a HP-like calculator. The app supports a scarce number of operations, but the interface is simple to get used to.
