## numeral system with ten as its base / From Wikipedia, the free encyclopedia

The **decimal** numeral system is the most usual way of writing numbers. It has ten as a starting point, or base. It is sometimes called the **base ten** or **denary** numeral system. The word "decimal" is also used to mean the dot (".") that is sometimes used to separate the positions of the numbers in this system. Indeed, the dot is the default decimal separator in English-speaking countries.^{[1]}^{[2]}
