  Integer - Wikipedia, the free encyclopedia
The term rational integer is used, in algebraic number theory, to distinguish these 'ordinary' integers, in the rational numbers, from other concepts such as the Gaussian integers.
The lack of multiplicative inverses, which is equivalent to the fact that Z is not closed under division, means that Z is not a field.
The integer q is called the quotient and r is called the remainder, resulting from division of a by b.

 Integer   (Site not responding. Last check: 2007-10-26)
The integers consist of the natural numbers (0 1 2...) and their negatives (−1 −2 −3...; −0 is to 0 and therefore not included as separate integer).
Integer datatypes are implemented using a fixed number of bits and even variable-length representations eventually run of storage space when trying to represent large numbers.
Integer programming is one of the most interesting subjects and this book captures the beauty of it through the use of nice explanations and a neat and organised notation.

 Integer (computer science) - Wikipedia, the free encyclopedia
In computer science, the term integer is used to refer to any data type which can represent some subset of the mathematical integers.
The most common representation of a positive integer is a string of bits, using the binary numeral system.
Another, rather different, representation for integers is binary-coded decimal, which is still commonly used in mainframe financial applications and in databases.

 PHP: Integers - Manual
An integer is a number of the set Z = {..., -2, -1, 0, 1, 2,...}.
Integers can be specified in decimal (10-based), hexadecimal (16-based) or octal (8-based) notation, optionally preceded by a sign (- or +).
The size of an integer is platform-dependent, although a maximum value of about two billion is the usual value (that's 32 bits signed).

 Combinatorial and Integer Optimization   (Site not responding. Last check: 2007-10-26)
Since there are often different ways of mathematically representing the same problem, and since obtaining an optimal solution to a large integer programming problem in a reasonable amount of computer time may well depend on the way it is "formulated", much recent research has been directed toward the reformulation of integer programming problems.
The major components of this algorithm consist of automatic reformulation procedures, heuristics which provide "good" feasible integer solutions, and cutting plane procedures which tighten the linear programming relaxation to the combinatorial problem under consideration -- all of which is embedded into a tree-search framework as in the branch-and-bound approach to integer programming.
The cutting planes generated by the algorithm are facets of the convex hull of feasible integer solutions or good polyhedral approximations thereof and as such they are the "tightest cuts" possible.

 2.4.4 Integer and long integer literals
Plain integer literals that are above the largest representable plain integer (e.g., 2147483647 when using 32-bit arithmetic) are accepted as if they were long integers instead.
There is no limit for long integer literals apart from what can be stored in available memory.
In versions of Python prior to 2.4, octal and hexadecimal literals in the range just above the largest representable plain integer but below the largest unsigned 32-bit number (on a machine using 32-bit arithmetic), 4294967296, were taken as the negative plain integer obtained by subtracting 4294967296 from their unsigned value.
