Integer (computer Science)

In computer science, an integer is a datum of integral data type, a data type which represents some finite subset of the mathematical integers. Integral data types may be of different sizes and may or may not be allowed to contain negative values. Integers are commonly represented in a computer as a group of binary digits. The size of the grouping varies but computer hardware nearly always provides a way to represent a processor register, or memory address as an integer; the set of integer sizes available varies between different types of computers.
