One of the numbers ..., , , 0, 1, 2, .... The Set of Integers forms a Ring which isdenoted . A given Integer may be Negative (), Nonnegative (),Zero (), or Positive (). The Ring has Cardinality ofAleph-0. The Generating Function for the Nonnegative Integers is

There are several symbols used to perform operations having to do with conversion between Real Numbers and integers. The symbol (``Floor '') means ``the largest integernot greater than ,'' i.e., int(x) in computer parlance. The symbol means ``the nearest integer to ''(Nint), i.e., nint(x) in computer parlance. The symbol (``Ceiling '') means ``the smallest integer not smaller ,'' or -int(-x), where int(x) is theInteger Part of .
