PCalc is ideal for scientists, engineers, students, programmers, or indeed anybody looking for a feature rich calculator for the iPhone or iPod Touch.

It includes an extensive set of unit conversions, a paper tape, an RPN mode, engineering and scientific notation, as well as support for hexadecimal, octal and binary calculations.

Whats new in version 1.02:
The most notable new feature in this release is support for multiple undo and redo. All you need to do is flick the LCD display to the right to undo, or to the left to redo,
The RPN mode has been improved, with the “HP style RPN” option available to make PCalc behave more like your trusty old calculator.
You can also now change the colors of the LCD - simulate that old red LED calculator, or just choose a simple black on white display.
In addition, the calculator keys have been made more readable, and the layout improved.
PCalc is available to buy today at $9.99 from the iTunes Application Store.
