   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.

The Free On-line Dictionary of Computing (19 January 2023):

integer
whole number

    (Or "whole number") One of the numbers in the set

    ..., -3, -2, -1, 0, 1, 2, 3, ...

   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.

   Computers are particularly fast when operating on integers as
   the operations are built into the central processing unit,
   in contrast to floating point numbers, which typically
   require the use of a separate floating-point unit.
