 Some locales use context-sensitive formats for numbers, which Django's

-The Swiss number formatting depends on the type of number that is being
-formatted. For monetary values, a comma is used as the thousand separator and
-a decimal point for the decimal separator. For all other numbers, a comma is

+example, monetary values may use a dot as decimal separator (``Fr. 23.50``),
+while measurements often use a comma (``22,5 m``). Django’s localization system
