Do you use comma or dot to mark thousands?

Hi dorann, it was taught the other way around in Indonesia. I use comma to sign thousands and dots to sign decimal numbers. For example if I want to write 1 million, I'll write 1.000.000,00. Anyway, i found this explanation from wiki The following examples show the decimal separator and the thousands separator; the lists are ordered chronologically, by when each country adopted the use: In Serbia[citation needed], Croatia, Bosnia, Estonia, France, Finland, Hungary, Poland, Czech Republic, Slovakia and much of Latin Europe as well as French Canada: 1 234 567,89 (In Spain, in handwriting it is also common to use an upper comma: 1.234.567'89)[citation needed] In Germany, Belgium, Denmark, Italy, Romania, Sweden and much of Europe: 1 234 567,89 or 1.234.567,89 (in handwriting, 1?234?567,89 is also seen[citation needed], but never in Denmark or Sweden) In the Netherlands: for currencies the thousands separator is a dot, e.g. EUR 1.234.567,89, but for other numbers a (narrow) space is used, e.g. 1 234 567,89 In Switzerland: 1'234'567.89; for thousand separator an apostrophe is used. In Australia, English Canada, Israel, Japan, Korea (both), Malaysia, Singapore, the Philippines, the United Kingdom, and the United States: 1,234,567.89 or 1,234,567·89; the latter is more commonly found in older, and especially handwritten, documents; many British and Canadian schools now teach the SI style with a dot separator, which has become official in Australia. Australia also now teaches the use of a space as a thousands separator i.e. 1 234 567.89 SI style: 1 234 567.89 or 1 234 567,89 (in their own publications the dot is used in the English version and the comma in the French version). In Chinese, comma and space are used to mark digit groups because dot is used as decimal separator. There is no universal convention on digit grouping, so both thousands grouping and no digit grouping can be found. However, grouping can also be done every four digits: 123,4567.89, since names for large numbers in Chinese are based on powers of 10,000 (e.g. the next new word is for 108). Japan is similar.
