PCalc 4 is a brand new version of my veteran calculator application.
It is a fully featured scientific calculator for OS X with support for hexadecimal, octal and binary calculations, as well as an optional RPN mode, parentheses, programmable functions, and an extensive set of unit conversions.
- Switchable button layouts - choose from many different horizontal and vertical layouts to suit your needs. Includes all the layouts from the iPhone and iPad, as well as Mac-specific ones.
- Calculator themes - pick your look, all the way from minimalist to striking.
- An RPN mode with one button access to the stack, and optional multiple-line display.
- Editable user conversions, functions, and constants which are synced automatically across multiple devices.
- Hexadecimal, octal and binary modes, complete with a variety of bitwise operators.
- A simulated paper tape to keep track of your calculations with a "ticker tape" mode under the main display.
- Smart searching of conversions, functions, and constants. Just search for "$ to £" for example.
- Stylish, consistent user interface.
- Support for Retina displays.
- Full AppleScript support.
- Multiple undo and redo.
- Modern 64-bit Cocoa application.

It costs $9.99 in the US, price varies in other countries. TLA Systems employs me and my wife Saskia full time, so paying for your copies of PCalc and DragThing really does make a difference to us!
