   Usage: Whole, Total, Entire, Complete. When we use
          the word whole, we refer to a thing as made up of
          parts, none of which are wanting; as, a whole week; a
          whole year; the whole creation. When we use the word
          total, we have reference to all as taken together, and
          forming a single totality; as, the total amount; the
          total income. When we speak of a thing as entire, we
          have no reference to parts at all, but regard the
          thing as an integer, i. e., continuous or unbroken;
          as, an entire year; entire prosperity. When we speak
          of a thing as complete, there is reference to some
          progress which results in a filling out to some end or
          object, or a perfected state with no deficiency; as,
          complete success; a complete victory.
          [1913 Webster]

whole number

   There are an infinite number of integers, though each one is
   finite.

   An inductive definition of an integer is a number that is either
   zero or an integer plus or minus one.  An integer has no
   fractional part.  If written as a real number, e.g. 42.0, the
   part after the decimal point will be zero.

   A natural number is a non-negative integer.

   Computers usually store integers in binary.  Natural numbers can
   be stored as unsigned integers and integers that may be negative
   require a sign bit and typically use twos complement
   representation.  Other representations have been used, such as
   binary-coded decimal.
