Besides, you don't need to write non-significant zeroes !
Clarification for monolingual readers: in many languages "." and "," in numbers are reversed relative to their use in English.

Actually, we use "," for comma separator, but we don't use "." for thousands separator. Either we use no thousand separator (for 4 digits) or we use... space (thin insecable space). At least this one is non ambiguous.

Yes, and I see I have badly oversimplified[1].

I've even seen other variants, with the use of the dot not on the base line but higher, in the middle of the line, or the use of the apostrophe as thousand separator.

Actually, I use comma as decimal separator but have no problem reading numbers that use dot instead.
On the other hand, I'm lost as soon as some one uses the comma as thousand separator (and when it's mixed with dots, I crash).
