Introduction
PCalc 3 is a brand new version of my veteran calculator application from 1992. It is a fully featured scientific calculator for Mac OS X with support for hexadecimal, octal and binary calculations, as well as an RPN mode, parentheses, programmable functions, and an extensive set of unit conversions.
PCalc was the first piece of Macintosh software I ever wrote - I started it in the summer of 1992 to learn how to program the Mac while I was at university. It has been rewritten from scratch twice now. The first time was in 2000 with the release of PCalc 2, so I could learn about programming Mac OS X. A special release of PCalc 2 was included by Apple with Macs sold in the US and some other countries during 2002.
With PCalc 3, I've rewritten it once again to take advantage of many years of advancements in Mac OS X.
