How the world separates its decimals

Thematic Maps, Numbers

Many countries use a dot to represent a decimal point e.g. 4353.56.
Many countries instead use a comma to represent a decimal point e.g. 4353,56.

The following thematic map shows the official decimal separation standards for each country.

Some countries use a mix of commas and dots for different situations.  For example, Switzerland uses commas unless dealing with Swiss francs (their currency).
