Ternary numeral system
From Free net encyclopedia
Template:Table Numeral Systems Ternary or trinary is the base-Template:Num numeral system. Ternary digits are known as trits (trinary digit), with a name analogous to "bit". Although ternary most often refers to a system in which the three digits, Template:Num, Template:Num, and Template:Num, are all nonnegative integers, the adjective also lends its name to the balanced ternary system, used in comparison logic and ternary computers.

Compact ternary representation: base 9 and 27
Ternary is inefficient for human usage, just as binary is. Therefore, nonary (base 9, each digit is two ternary digits) or septemvigesimal (base 27, each digit is three ternary digits) is often used, similar to how octal and hexadecimal systems are used in place of binary. Ternary also has a unit similar to a byte, the tryte, which is six ternary digits.
