An integer may comprise a set of whole numbers that include zero, positive number and negative number. We draw the zero in a line and put the positive numbers on the right and the negative numbers on the left: As $$-7$$ is the one on the far left, then we can see that it is the smallest. A treatment of computational precision, number representation, and large integers … The integers are made up of positive numbers, negative numbers and zero. Intuitively, I would say "the set of the integers", because "a set of integers" could refer to just any set consisting of integers, say {1, 2, 3}, and so "the set of integers" could refer to some set consisting of (not necessarily all) integers which was introduced earlier. In short, the set formed by the negative integers, the number zero and the positive integers (or natural numbers) is called the set of integers. This terminology a common point of confusion. 32 bit). From this definition, it is easily visible that the set {1,3,5} is a subset of the set of odd integers since 1, 3 and 5 are also members of the larger set.
