What Does Decimal Point Mean?
With a decimal number system, a decimal point is used to denote the decimal part of the number. Unlike the separators used for digit grouping such as the thousands separator, no separators are used to the right of the decimal point. Different countries officially designate different symbols for the decimal point. In most English-speaking countries, the decimal point is usually denoted by a period/dot to separate the whole number from its fractional parts. However, in continental Europe, the decimal point is usually denoted with the comma.

The choice of symbol for the decimal point affects the choice of symbol for the thousands separator, which is largely used in digit grouping. Unicode has provided a decimal separator key symbol which is similar to the apostrophe. It is intended for usage on the keyboard in order to perform decimal separation.
