What's New in Version 4.3
Added full support for OS X 10.11 El Capitan.
Added an option to float the PCalc window above all other apps.
Added the "Split Screen iPad" layouts from PCalc on iOS 9.
Added a delta percentage button to most layouts as the 2nd function of percentage.
You can now paste simple calculations into PCalc.
Changed behaviour of the percentage key in algebraic mode to match the Apple calculator - old behaviour still available via "Display percentage result" option in Advanced section of Preferences.
Now display "Error" rather than just blinking the display on an incorrect operation.
Fixed a problem editing user functions and conversions with conditional skip commands.
Core code has been updated to match PCalc 3.5 on iOS.
Best Mac Calculater Ever (Literally)!
Been a PCalc user from the old Macintosh SE days. It was the best straight-up calculator for the Mac back then, and still is now.
Yes, the “natural language” calculators are powerful and better suited for more narrative mathematical tasks, but more often than not, I just need to crunch numbers. PCalc lets me do that simply, attractively, and in my preferred way.
Worth every penny!
PCalc is better than the Apple calculator in almost every way. However, it does not work with spotlight, which is a big inconvenience. If it gains spotlight support, I’ll change my rating to a 5.
Best in Class
I am not a frequent calculator user but when I need one, I need power. This has been my mainstay for I think well over a decade.
