unary
adj 1: consisting of or involving a single element or component;
"in a unary operation in a mathematical system one
element is used to yield a single result"

1. (or "{monadic}") A description of a
{function} or {operator} which takes one {argument}, e.g. the
unary minus operator which negates its argument. The term is
part of the same sequence as {nullary} and {binary}.

2. Base one. A number base with only one
digit, namely zero, and which can therefore only be used to
express the number zero. Attempting to add one to zero
results in an infinite sequence of carries. Numbers in unary
notation can be represented particularly efficiently however
since each digit requires no storage.
