Version: (using KDE Devel) Installed from: Compiled sources When switching to conversion mode in KBruch, the decimal is shown as, for example "0,3", with a comma as the decimal separator, regardless of the l10n setting. This is because the strings are hardcoded in kdeedu/kbruch/src/exerciseconvert.cpp, lines 200 ff.
I will fix it next week.
