Great Britain and the United States are two of the few countries that use a period (.) as the decimal separator, while many others use a comma (,), often referred to as the radix character. Similarly, the U.K. and U.S. use a comma to separate groups of thousands, whereas many countries use a period or a thin space. Scandinavian countries and French-speaking Canada prefer a space as a thousands separator, while Thailand follows the US system. The table below illustrates some of the most commonly used numeric conventions worldwide.
