I frequently use KRunner to do simple sums when doing my accounting. I keep a ledger with numbers formatted as e.g. 1,000.00. My system settings in KDE for number formatting under Region & Language is set to British English, i.e. the way I want it. However, whenever I copy a sum from KRunner, e.g. “1000.25 + 1000.25”, it is copied as “2000,5” (i.e. no thousands-delimiter, wrong decimal point and only one decimal number). It gets a bit annoying to change this manually.

I can’t seen to find any specific settings for this in KRunner or the Calculator plugin, and I would expect it to respect KDE’s own settings.

Does anyone know how to force KRunner to do my bidding here?
