omg KDE if it ain't broken, fix it until it is?

Another case of abusing the word "enshitification"

If you think you have found a bug, please report it at https://bugs.kde.org. This is will help get it solved as opposed to every other course of action.

What did you do to get this "Input Error"?

To be honest, I tried really hard to give it a try to Kcalc but I give up. Check out Kalk (no, no it's the same), it's a KDE Calculator and it's preatty neat IMO.

I don't know what this image is supposed to tell us, but I can confirm that KCalc behaves badly in some common situations. (At least, it does in Plasma 5.) Want to see an example?

Put it in Simple Mode, and try copying and pasting various multi-digit numbers with leading zeroes. Some of them work fine. Others, like 054 and 009, yield surprising results.

A programmer or mathematician might be able to deduce that KCalc is trying to interpret those numbers as octal (base 8 instead of base 10), if they're paying close attention. That doesn't help anyone who is just trying to total a bunch of numbers from a document, using their default desktop calculator, and doesn't notice a misinterpreted value along the way. Their total will just be wrong, or in the case of nan, they will just be frustrated that the calculator doesn't work.

This behavior is probably not appropriate for Simple Mode.

It does the same thing even in Numerical System Mode with decimal (base 10) explicitly selected, which is absolutely not appropriate.

Try Qalculate, it is extremely powerful and better that anything else imo

@kde solved by running "sudo downgrade kcalc" and selecting the latest 22.x version and adding kcalc to IgnorePkg

yes it's brutal, but breaking a11y support is worse

@kde what's this new input line for? does it solve a problem? how can I get rid of it?
