  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 part, a decimal

  point, a fractional part 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
