Platform: Other

Assignee: plasma-b...@kde.org

SUMMARY
When converting certain values, the unit converter in KRunner shows a rounded
value in the result list, but when pressing the suggestion to copy it, it will
copy a number with floating point precision errors. Either the displayed value
should be copied to the clipboard or the unit converter should work with
arbitrary floating point numbers instead
STEPS TO REPRODUCE
1. Open KRunner
2. Enter 5.1mm
3. Click the 0.0051m option
OBSERVED RESULT
0.0050999999999999995 is copied to the clipboard
EXPECTED RESULT
0.0051m should be copied to the clipboard.
