Description postix 2024-11-16 13:48:31 UTC 
STEPS TO REPRODUCE
1. Open krunner, type: 1 + sqrt(2) or 1 + sin(2)
2.  Try the same with sqrt(2) + 1 or sin(2) + 1

OBSERVED RESULT
1. It asks to search with $websearchengine 
2. It calculates correctly

Works fine with qalculate-qt, which uses the same lib.

This is an issue in Libqalculate, which is the library we use for mathematical calculations under the hood. Can you report this at https://github.com/Qalculate/libqalculate/issues? Thanks!

As I wrote

two things come in my mind: this is either a regression in Libqalculate, no one has reported yet OR this is a parsing error in krunner and I assume it's the latter.

Eek, sorry for missing that part.
