  A character may be viewed as an

  alphanumeric entity, i.e:

     a, A, c, D, K, 0, j, @, -, . , etc. 

  -------------------------------------------

  An integer may be viewed as a whole number

  fitting in your machine's integer set, i.e:

              -15, 2347, 0, 17, -249

  A floating point number may be viewed as a

  number with an integer, a decimal point, a 

  fraction, and/or an exponent, i.e:

        -237.6,    -0.0017,    3.24,   17E17

 ----------------------------------------------

  A double precision floating point number

  has the same properties as the float,

  however it occupies twice as much space in memory, i.e:

  float     -237.6            3.24

  double          -237.6           3.24
