SUMMARY When using en_GB system language but with es_ES (Spanish) keyboard, the numpad dot (.) does not input anything in the calculator field. If I type the decimal separator using the main keyboard's comma key (,) then the comma is written in the input field. Gnome calculator for example does work as expected and just writes the decimal comma despite pressing the numpad dot. STEPS TO REPRODUCE 1. Set keyboard or language locale to one that uses comma (,) as a decimal separator. 2. Input in KDE Calculator a number with decimals using the numpad dot (.). OBSERVED RESULT No decimal separator is written, no input. EXPECTED RESULT A comma/dot written as decimal separator, regarless of whether decimal separator for the system is dot or comma.
