  From  WordNet  r  1.6  [wn]: 
 
  unary 
  adj  :  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" 
 
  From  The  Free  On-line  Dictionary  of  Computing  (13  Mar  01)  [foldoc]: 
 
  unary 
 
  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.
