There just isn’t a shortage of calculator apps for Mac users to choose. Most are free, and many cost only a few dollars.
Why would you want to pay for a calculator? I just did and I’m loving it. Based on a recommendation from a co-worker, I downloaded PCalc for both my Mac and iPhone. What can I say? It’s a calculator with super powers. PCalc is a scriptable scientific calculator. It supports octal and binary calculations, as well as hexadecimal calculations.
Even better, there’s an RPN mode (reverse Polish notation) with a bunch of programmable functions, and a full set of unit conversions.
Big whoop, right? Visually, though, PCalc boasts a usability factor that exceeds that of most calculators.
PCalc is the closest thing to a real, physical calculator in the digital world of your Mac’s screen. There’s a small layout, a basic layout (smaller), and the larger default layout.
The buttons are clearly labeled and easily identifiable. There’s a built-in tape of your string of calculators so you can do a quick audit.
Decimal, Hex, Octal, and Binary are displayed in a pop down pane. Number sizes, styles, and colors can be customized to match your needs.
For power users, there’s a full on supply of keyboard shortcuts so you won’t have to point and click.
PCalc’s conversions are straightforward and simple to navigate. Select what you want to convert, select the From and To and click the Convert button.
Preferences are modest, but include an option to use multiple memories, clear the calculator at startup (otherwise it remembers), change the display digits, and a slider is used to adjust decimal places.
Even better, there’s a Dashboard Widget for PCalc which makes quick work of simple calculations. This is the calculator Apple would have designed for the Mac but someone beat them to it.
