From TLA Systems:
PCalc 3 is a fully featured scriptable scientific calculator for Mac OS X with support for hexadecimal, octal and binary calculations, as well as an RPN mode, programmable functions, and an extensive set of unit conversions. A Dashboard Widget is included with the main application. A special version of the previous PCalc 2 release was included by Apple with most Macs sold in the US during 2002.
What's new in this version:
- Gamma function now works on a wider range of inputs.
- Fixed a problem with the Dashboard Widget not saving some preferences.
- Updated with the latest code from PCalc 1.8.1 for iPhone / iPod Touch.
