  scalar
       
          1.  A single number, as opposed to a vector or
          matrix of numbers.  Thus, for example, "scalar
          multiplication" refers to the operation of multiplying one
          number (one scalar) by another and is used to contrast this
          with "matrix multiplication" etc.
       
          2.  In a parallel processor or vector
          processor, the "scalar processor" handles all the sequential
          operations - those which cannot be parallelised or vectorised.
       
          See also superscalar.
       
          3.  Any data type that stores a single value
          (e.g. a number or Boolean), as opposed to an aggregate
          data type that has many elements.  A string is regarded as a
          scalar in some languages (e.g. Perl) and a vector of
          characters in others (e.g. C).
