unwary

adj : not alert to danger or deception; "the shrieks of unwary

animals taken by surprise"; "some thieves prey

especially on unwary travelers"; "seduce the unwary

reader into easy acquiescence"- O.J.Campbell [ant: {wary}]

unary

1. A description of an {operator} which takes

one argument, e.g. the unary minus operator which negates its

argument.

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.
