PCalc is the powerful choice for scientists, engineers, students, programmers, or indeed anybody looking for a feature rich calculator. It includes an optional RPN mode and multi-line display, a choice of button layouts, an extensive set of unit conversions and constants, a paper tape, multiple undo and redo, engineering and scientific notation, as well as support for hexadecimal, octal, and binary calculations.

Release Notes

Fixed a problem with PCalc not responding to touches the first time it was opened.

New in 3.2:
Updated the core calculator code to match PCalc 4 on OS X.
Smart searching for conversions, constants, and functions - try "£ to $" in the search field, for example.
User functions and conversions can now access the RPN stack, use bitwise operators, and get and set values on the clipboard.
Now show a double zero key instead of an "Exp" key when in accounting mode.
You can now choose to automatically display big or small numbers in engineering mode, rather than scientific.
You can now add notes to the tape.
You can now specify which themes are used for the automatic night mode.
Added an option to switch to night mode based on the current screen brightness.

Added a "Last" key in algebraic mode which retrieves the result from the last time you pressed equals.
Added an option to display the ticker tape at the top of the display.
