Definition

1. Noun:
   • A digit from 0 to 11 in duodecimal notation: A duodecimal digit is a single symbol used to represent a numerical value in the base-12 (duodecimal) number system. This system requires twelve distinct digit symbols, typically 0 through 9 and then two additional symbols (often represented as A and B, or other notations, for the values ten and eleven).

Usage Examples

• Noun:
  • In duodecimal, the digit 'A' represents the decimal value ten.
  • To write the decimal number fifteen in duodecimal notation, you use the digits '1' and '3', making it '13'.
  • The duodecimal digits are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, and B.

Advanced Usage

• In mathematical contexts: The concept is primarily used in discussions of alternative numeral systems, computer science (e.g., some historical or specialized computing applications), and theoretical mathematics.
  • The advantage of a duodecimal system is that 12 has more divisors than 10, which can simplify fractions.

Variants and Related Words

• Duodecimal (adj): Relating to or based on the number twelve.
  • A duodecimal clock divides the day into two sets of twelve hours.
• Duodecimal system/notation (n): The base-12 positional numeral system.

Synonyms

• Base-12 digit: A digit used in the base-12 number system. (This is a direct synonym describing the same concept.)

Related Phrases and Concepts

• Place value in duodecimal: The value of a digit depends on its position, multiplied by powers of twelve.
  • In the duodecimal number '1A', the '1' represents one twelve, and the 'A' represents ten units.
• Carry-over/Regrouping in duodecimal: The process in arithmetic when a sum of digits in a column reaches or exceeds twelve.
  • When adding duodecimal digits, remember that 9 + A results in 17 (decimal), which is '15' in duodecimal, so you write down '5' and carry the '1'.
