Description Dave 2026-02-03 17:35:59 UTC 
SUMMARY
I used to use kcalc for converting between hexadecimal and decimal all the time but this feature went with the individual number base select buttons. I used to be able to add decimal and hexadecimal numbers using this feature.

STEPS TO REPRODUCE
1. enter FFFFFFFF in hex mode
2. switch to decimal mode
3. 

OBSERVED RESULT
The FFFFFFFF remains in the display and pressing any keys displays syntax error although the small display at the bottom gives decimal, octal and binary these displays are useless because I cannot copy them to paste into a file

EXPECTED RESULT
The FFFFFFFF is replaced by 4294967295

Right click and copy does work and by pasting back into kcalc I can perform calculations. This is a workaround, thanks
