[Post-Install] KCalc

[vanadiumboy]

Problem 1:
If I do any calculation, such as
1 + 1 =

and I try to copy the result by clicking Edit -> Copy
the result doesn't get copied to the clipboard. This was working with Kubuntu 24.04


Problem 2:
If I press 1000
press divide
press 5
press the exponent button (it is written x 10^y on the button)
press 8

the result is 20,000,000,000 (20 billion)

instead of 2e-06

As to getting KCalc to display results as scientific notation:

Adjusting Precision Limits

If you want KCalc to seamlessly switch to scientific notation only when numbers exceed a specific length:

• Go to Settings → Configure KCalc...

• Under the General tab, look for Precision (Maximum number of digits displayed).

• KCalc is designed to automatically trigger scientific notation (e.g., 2.34e12) once a calculated number surpasses this defined digit threshold. You can lower this value if you want it to trigger sooner.

Making this setting change doesn't affect what you have already displayed. You can Edit the entered values and delete the last one and reenter that input and the output will change to scientific notation.

I can reproduce this behavior.
It doesn't work to highlight and right click copy.
It doesn't work to highlight --> click Edit --> Copy in the Main Toolbar.
It does work with this: Ctrl+C

I haven't searched yet. Is there a bug report for this?

I found one bug report, but it's from 2024, shows it's assigned, but that's it. Only the initial report. It is with Kcalc on KDE neon. So based on this one report from 2024, seems that this issue has been around for some time! Bug 492680 can't copy calculation result as expected

i just tried it , if i go 1+1 = the answer is 2
if i highlight the 2 and press ctrl+c ,it copies to clipboard

also if i go 1+1 the answer shows below (2) , if i then click in the block with the 2 in , it'll blink , then press ctrl+c it copies the 2 to clipboard (no need to highlight the 2)

You actually don't need to press ctrl+c. The act of clicking in that box copies the value to the Clipboard. I just verified that.
