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.
Added support for macOS 13.
Added an "EV Efficiency" section to the conversions.
Now interpret text starting with "0x", "0o", or "0b" as hex, octal, and binary numbers.
Fixed an ambiguity when displaying some currency symbols like Yen and Yuan.
Fixed a problem with the "Round to Floor" and "Round to Ceiling" user function commands with negative numbers.
Fixed a problem with the "Modulo" function with negative numbers.
Ratings and Reviews
The only calculator app you need
I've been using this app for far longer than I can remember, but unlike my memory, PCalc just keeps getting better and better. Whenever there is a major mac or iOS (I also own PCalc on mobile) operating system version, PCalc is consistently one of the few apps that are ready and updated on day 1. The app itself has been incredibly stable. There are more tools in the app than I know what to do with. And now with version 4.9, there are even more customizations available. This app offers so much value for the price paid; and all of the above can be said about the mobile version of the app.
PCalc 4.5.3 on 10.8 bug
This is really a great app, but I'm using 10.8.5 Mountain Lion, yes I know it's an old os, and there's a bug I noticed.
About a third of the time opening the app, the number screen comes up blank. Not with a zero or anything else, just blank.
After a few more times of closing then opening, it works fine again, finally showing numbers. Is this just a Mountain Lion bug,
or is anyone else having this problem? Oh well, it actually works sometime, just wondered if anyone else has experienced this too.
I'm using version 4.5.3.
ALL TIME GREATEST CALCULATOR
If you’re an engineer, programmer, scientist, number lover, or calculator fanatic then welcome home. This app is for you. You will be giddy with happiness from the functionality and ui. You will experience joy you never thought a calculator could possibly bring you. It can even calculate the ultimate number.
-To the devs, thank you so much. I’m estatic that I found this app. It’s like my years of frustrated search has concluded. A search I didn’t realize existed until I found this. I never have to switch calculators or get frustrated from limits.
