I loved this on Windows but haven't used it since switching to macOS since it seems to not support Retina screens very well, anyone know of a workaround?

Heh, just came here to see if anyone else noticed the blurriness of the app on Mac.

Yeah, did a screenshot just to see what was up. Very blurry/chunky on Mac OS. Must be the UI library they use for Mac.

Earlier quoted context omitted.

Is that not correct? I guess I should touch on my order of operations. I thought distributing was part of the parenthesis step, that came before MDAS.

The disconnect is that a lot of people mentally treat implicit multiplication with a higher priority than explicit, which is pretty understandable. For instance: 1/3x is likely to be understood as 1/(3*x), because otherwise it would’ve been written like x/3. If that’s true, then so surely 1/3(x) should be the same, right? Smarter people than I have argued both sides of this, and I don’t have a strong opinion except t…

I would be confused if 1/2gt^2 would mean anything but 1/2 g t^2 and 0.5 g t^2. 1/3x in isolation may look a bit unusual, but with context the choice between 1/3 x and x / 3 may actually convey additional information, information about the structure of the calculation. Manipulating an equation into some kind of normal form may lose information.

I used to use this back when I mained Windows. Ever since moving primarily to Linux, and getting familiar with Emacs, Calc mode simply beats every calculator I've ever used in total functionality. However, there are certain cases where I also like to use https://insect.sh if lots of units are involved.

qalculate is by far the best calculator program I've ever used.

Agreed. This is one case that's not hyperbole.

I've been using and loving qalculate for years as part of Debian but strangely it isn't in the current Debian stable package list (bullseye). So I just switched to SpeedCrunch and it seems like a good replacement for most quick calculations where you still want to see some history.

A small plug for my own script: I'm proud to present the most useful, least-work script I've ever written: `math` https://github.com/shawwn/scrap/blob/master/math #!/bin/sh scale=4 # results will print to the 4th decimal echo "scale=$scale; $@" | bc -l It just yeets all its arguments into bc -l, so you can run math 1+2-3 or math '(1024 - 7)*10' or whatever else you want. I even use it in other shell scripts, since ba…

Wait, what!? I have never used an iPad but this just floors me.

Imagine going to an Apple store, asking about the new iPad, listening to the pitch, nodding along as they play fruit ninja and draw a smiley face with a stylus and then asking "what's the 12th digit of the square root of two?".

How can it not have a calculator? I mean, what?

I'm old and jaded and consumer grade technology hasn't amazed me or made my life better in well over a decade but this is a whole new level.

Emacs Calc (not unlike much of the rest of Emacs) is a little ... special. By default, it calculates 4/2*2 as 1, because multiplication has a higher precedence than division. https://orgmode.org/manual/Formula-syntax-for-Calc.html

You could open an issue. Seems like a reasonable idea to fix that.

This would be amazing on iOS. I saw an issues thread from 2017 ( https://bitbucket.org/heldercorreia/speedcrunch/issues/702/s... ) that discussed porting to iOS but nothing since. What are the GPL implications of porting this to Swift even with putting all source on a public GitHub/BitBucket repo because of the App Store?

VLC does it.

The fix for this is detailed in this thread: https://bitbucket.org/heldercorreia/speedcrunch/issues/716/v...

And the .dmg file that has the retina fix is here: https://github.com/gagarcr/speedcrunch-nightlies/releases

Hopefully this helps!
