Yes, indeed. Why create a problem when none exists.  A language should
have number formats cast in stone once and for all. For example,
accepting only "." as a decimal separator, only "-" for negative
numbers, etc. If a user-input facing API has to be locale specific, an
explicit adapter function should be used to translate strings as
needed.
