## Numeric Separators

In North America, the comma is used as a thousands separator, and the period is used as the decimal point. For example, 1,000.50 would be one thousand and fifty cents.

Many countries use the opposite convention, with a period as the thousands separator and a comma as the decimal point. For example, 1.000,50 would be read as one thousand and fifty cents.
