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:
- Dozens of new unit conversions, including all the currency conversions from the iPhone/iPad version.
- A number of new functions including a mod operator.
- Two new stylish calculator themes.
- Various fixes, not least of which is that copy and paste in the Dashboard Widget is now finally working again.
