I'm old enough to have relied on several calculators like that, but I don't remember any functions. I didn't use anything fancier than trig functions.

After a calculation, if you type another digit, it appends it to the register. What the heck is the new feld below the register? It seems to hold the running result. Yeah, you can click on that. It's also completely editable. You can position the cursor with the mouse and even insert operations between digits. It would be really cool if it would reset after pressing =. The main problem is having to manually clear after every calculation.

So, apparently I have to retrain myself to press Esc after copying instead of pressing = before. Esc is the same as the C button. Del is the same as the CA button. Pressing = or Enter sends the results to the history "tape", but I don't see what else it does.

What happened to Kcalc (lemmy.kde.social)
submitted 2 months ago* (last edited 2 months ago) by josephj11@lemmy.kde.social to c/kde@lemmy.ml
 

I use Kcalc many times every day. It worked great. I use it in Simple mode. When they added the history display, I started using it from flatpaks to get that feature in older releases.

On Kubuntu 22.04, I am using Kcalc 23.04.3. It works exactly the way it used to - which is what I want.

On Kubuntu 18.04, I'm using Kcalc 24.05.2. It does not work as expected or desired.

I have no idea why I have different versions on the two notebooks. AFAIK, I installed them the same way.

On the old version, if I enter 1 * 2 =, the answer, 2 appears in the register. Clicking on the register copies it to my clipboard. Entering another digit clears the register and replaces it with the new digit. The old calculation and results are automatically out of the way.

On the new version, if I enter 1 * 2 =, 2 appears in a new space below the register and then disappears from that space and 2 appears in the register. Clicking on the register appears to do nothing. I have to double or triple click on it to select it and then press Ctrl+C to copy it to my clipboard. This is bad. But far worse, if I next type a 3, instead of the register containing 3, it appends the 3 and the register contains 23. This means I have to clear the register every time before I use it.

I have never seen a calculator that does this and don't want to!

What is going on? Do I have to find a way to get and pin the old version?

Why was this done?

Where is the best place to file or add to an issue to get this reverted?

 

Claude.ai tells me that this exists but I don't see it on Kubuntu 18.04 or 22.04.

A checkbox or toggle switch labeled "Different widgets for each desktop" or "Separate widget sets for each desktop"

Is this real and what do I have to do to get to it?

x-y problem:

What I really want is a "sub-desktop" like a subfolder of a folder, but looking like a desktop - preferably without switching activities or opening an actual folder in Dolphin.

My problem is that with cryptocurrencies, I have icons for price URLs, icons for staking URLs, and icons for wallets. They're conceptually all part of one thing I'm doing, but there are too many to fit comfortably on one desktop.

And, I get them all arranged in groups on the screen exactly the way I want them and then I accidentally change resolution on an external monitor... and KDE rearranges them all in alphabetical order making the desktop almost useless.

At least if I could break them up into groups, it would be easier to recover from the above disaster.

Maybe having a bunch of activities would do it. I'm not sure how to approach this.

Thanks. That and megane-kun's solutions work, now that I know about the backslash key.

BTW, IDK about Kcalc 22, but Kcalc 23 rocks because they added history to it. If you type Ctrl+h, it opens a panel that shows all the past results since the last AC. That's why I'm using the flatpak to get it. It makes the calculator much easier to use and when I get ridiculous results, it shows me what I actually typed instead of what I meant to type.

 

I am doing some Bitcoin calculations where I enter integer values (Satoshis) and then need to multiply them by 10**-8 to get the value in Bitcoins, e.g. to calculate price in US dollars.

I don't see how to do this other than by saving 0.00000001 in my clipboard.

I sort of got positive exponents to work, but the exponent functionality disappears as soon as I type a minus sign for the exponent for 10**-8 because it gets interpreted as a subtraction operator instead of as a unary sign.

I can just divide by 10**8 which works, but it's not quite as intuitive for me.

Is there a better way to do this?

Is this a bug?

I'm using Kcalc 23.04.3 in a flatpak on Kubuntu 22.04.

I've got it working, but I have to use it a while to see if it's stable.

Sometimes asking a question makes you think of an answer.

I think I have a good workaround for now.

I'm writing an AutoKey script to do it using a Python regex. The added benefit of doing it this way is that it will work almost anywhere, not just in Kate.

 

I have a plain text journal/log that I write and edit in Kate. This contains a number of floating point numbers and I often copy and paste them into Kcalc or LibreOffice Calc.

I would like to be able to double click on one of them and have it all selected so I can copy it into the clipboard. This does not work because it only selects the digits on one side of the decimal or the other which forces me to use the mouse to select the whole number - which is slower and more work for me.

When I'm doing this, I'm doing it a lot, so speed makes a difference to me.

Is there a way to temporarily tell Kate that the period/decimal is a word character so the double click will work?

Some of my numbers also have commas in them as thousands separators for readability, so including the comma as a word character would be nice as well.

This behavior would not be good as a permanent setting unless I could restrict it to something like a particular Kate profile... because I need the normal behavior the rest of the time.

Any ideas would be appreciated.

It's an active part of the splash screen. I don't want to get rid of it. Since it only lasts a short time - much less than the whole splash screen, I was wondering if something particular was being done while it is displayed.

I have occasionally disabled splash screens and watched all the startup log entries fly by, but I don't want to see that unless something is seriously broken and I need to figure out what.

 

Part of the KDE login process on Kubuntu 22.04 shows me a gear spinner for a very short while. What does that signify? It still takes a while after it disappears before anything else happens.
