Pcalc

PCalc 2.2.2 is the latest version of my veteran scientific calculator application. It's a fully featured scientific calculator that works on Mac OS 8 and later, including native support for Mac OS X. It has a Reverse Polish Notation mode, and support for Binary, Octal and Hexadecimal calculations. 2.2.2 fixes a number of problems on Mac OS X, and with the help, and adds function key shortcuts for undo/cut/copy/paste and some new Euro currency conversions. It ships with a native Carbon version for Mac OS X, and a Classic version for Mac OS 8 and later. This release of PCalc is shareware, that means you can download it and try it out for free, but if you like it and continue to use it you should pay the US $10 registration fee.
