A calculator app might seem like a very small thing, but the availability of PCalc is literally one of the handful of items I have in my "pros/cons" list of using iPhone vs. an Android phone.
Per https://www.pcalc.com/mac/twenty.html, PCalc is 28 years old. That's a lot of time to get feedback, refine your design and add features, and repeat.
I don't know what RPN is btw.
This is a wonderful calculator for mac if you don't need the scientific bits.
I like Numi so much that I made a slightly worse, open source, mutliplatform version of it, that I use often.
- symbolic differentiation/integration
- conversion between units
- solving equations
- working with matrices
- rewrite systems
For example, "4*a(1)" to calculate pi.
- symbolic/numeric integration
- equation solving/manipulation
- unit conversion
- vectors and matrices
- functional array operations like map/reduce
- statistical operations
- a detailed manual
Personally my main use of bc is:
... | paste -s -d+ | bc

I get your previous comment wrong then
> Functions can also be inverted so that you can solve for their parameters. Note how we were able to use the one equation for Fahrenheit temperatures f to calculate a Celsius temperature c.
This looks really cool. Thanks for the recommendation
I just made the open source knock-off, as I use linux as well and wanted it on there too.
But I'm definitely going to take a look of the two you mentioned.
To my knowledge Soulver was the first one to apply this concept, but I haven't used it in so many years I wouldn't know how it compares to Numi, although it does seem to have more features.
I also use Soulver which has reimagined the calculator interface...you can just use it as a quick calculator, or do more complex calculations when a spreadsheet is too heavyweight, and then go back and edit prior entries.
And of course on the Mac you can do calculations right in spotlight (cmd-space 5 + 4) which is pretty low friction.
The coolest thing about Tydlig is that it shows the history and you can reference results from calculations by touch and drag, and then you can change the values used in past calculations and the calculations that depend on the values of those update. Kind of like a spreadsheet but without cells. I use it a lot.
Love it! Thanks again.
I was very happy, when they released an iOS version.
There’s also a Watch version (https://www.pcalc.com/ios/), so you can have a wrist calculator, like those old Casio watches.
PCalc is in that category. I can't speak for everything, but what I try to do when I use it on my iPad just works, so I've never thought about it. At least on the iPad, the list of keybindings are a tap or two away. I don't see an obvious way to change keys around, though you can move the buttons around.
(Don't take this as granted, of course, there are still iPad apps that are actively being updated that ignore the keyboard .. if everything that plays video would treat the spacebar as play/pause, I'd be much happier)
