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.

Includes an Apple Watch app, so you can calculate on your wrist!

What's New

Updated all scientific constants to the latest CODATA 2018 values, and now includes the full list.
Improved accuracy of stored numbers when PCalc isn't running, and for copying and pasting.
Improved the UI for using multiple memories in the watch app and widget.
You can now specify the setting for using multiple memories separately for the watch app and widget.
No longer show the "M" indicator when other memories have contents, but "Use Multiple Memories" is off.
Added new line display types that show a running total for the current calculation, the "Last X" value, and all the memories.
Added an option for displaying all function variables in the registers section.
Fixed a problem searching for functions, conversions, and constants.
