duodecimal number system
Definition
- Noun:
- A duodecimal number system is a positional numeral system that uses a base, or radix, of twelve. In this system, twelve distinct digits are required to represent all values. The number twelve is written as "10" in this system, as it represents one full group of twelve and zero units.

- The duodecimal number system is sometimes proposed as an alternative to the decimal system because twelve has more divisors than ten, which can simplify certain fractions.
