14602	Confusion between digit group separators and decimal marks	sommerluk	team	"In JOSM, settings, audio player, speed, I can see “1.3” and that seems to mean “one (and three tenth). In JOSM, settings, WMS/TMS, settings, cache size, I can see “20.000” and that means “twenty thousand”. So, sometimes the full stop “.” is used as digit group separator and sometimes it is used as decimal mark. That’s extremely confusing and definitively wrong.

Furthermore, this is also a localization issue. In some countries, “,” is the decimal mark, in others “.” is the decimal mark. The world seems to be divided fifty-fifty. As I’m using JOSM with the localization “German (Germany)”, so I would expect JOSM to use “,” as decimal mark, but JOSM doesn’t. Maybe it is intentionally that JOSM ignores the localization of the decimal mark, because Geo-URLs often use the decimal point as separator and JOSM doesn’t want to confuse the user furthermore?

Anyway, for digit group separators it would be a good idea to use always consistently (and independent of the localization) in all fields a space, just as ISO 31-0 tells. The character U+202F NARROW NO-BREAK SPACE might be a good space character to use.
