Nonary is a base 9 numeral system, typically using the digits 0-8, but not the digit 9. A numeral is a symbol or group of symbols that represents a number. ... In mathematics and computer science, a numerical digit is a symbol, e. ...

Nonary notation can be used as a concise representation of ternary data. This is similar to using quaternary notation for binary data, though the digit set is closer in size to octal. Ternary is the base 3 numeral system. ... Quaternary is the base four numeral system. ... The binary or base-two numeral system is a system for representing numbers in which a radix of two is used; that is, each digit in a binary numeral may have either of two different values. ... The octal numeral system is the base-8 number system, and uses the digits 0 to 7. ...
Except for three, no primes in nonary end in 0, 3 or 6, since any nonary number ending in 0, 3 or 6 is divisible by three. 3 (three) is a number, numeral, and glyph. ...
A nonary number is divisible by two, four or eight, if the sum of its digits are also divisible by two, four or eight respectively. 2 (two) is the natural number following 1 and preceding 3. ... 4 (four) is the natural number following 3 and preceding 5. ... 8 (eight) is the natural number following 7 and preceding 9. ...
However, they are still far less compact than the corresponding representations in bases such as decimal â see below for a compact way to codify ternary using nonary and septemvigesimal.
