# Integer Number vs. Whole Number — What's the Difference?

Edited by Tayyaba Rehman — By Fiza Rafique — Published on November 30, 2023
Integer Numbers include positive, negative numbers, and zero (e.g., -2, -1, 0, 1, 2). Whole Numbers are non-negative integers (e.g., 0, 1, 2).

## Key Differences

Integer Numbers are a broader category in mathematics that encompasses all positive numbers, negative numbers, and zero. They extend indefinitely in both positive and negative directions on the number line.
Whole Numbers, on the other hand, are a subset of the Integer Numbers. They only consist of positive numbers and zero. This means that while every Whole Number is an Integer Number, not every Integer Number is a Whole Number.
Integer Numbers can be visualized on a number line stretching infinitely in both directions. For instance, -3, -2, -1, 0, 1, 2, 3 are all Integer Numbers, showing their inclusivity of negative values.
Whole Numbers begin at zero and continue infinitely in the positive direction. 0, 1, 2, 3, and so on, are all Whole Numbers. They exclude any negative values, differentiating them from Integer Numbers.
Both Integer Numbers and Whole Numbers have their places in mathematics. While Integer Numbers are more comprehensive, including all values from negative infinity to positive infinity, Whole Numbers represent only non-negative values, including zero.

## Compare with Definitions

#### Integer Number

Integer Numbers are numbers without fractional parts.
-5 is an Integer Number as it doesn't have a decimal or fraction.

#### Whole Number

Every Whole Number is an Integer Number, but not vice versa.
4 is both a Whole Number and an Integer Number, but -4 is just an Integer Number.

#### Integer Number

Integer Numbers include both negative and positive numbers.
-8 and 8 are both Integer Numbers representing opposite values.

#### Whole Number

Whole Numbers start at zero and continue indefinitely in the positive direction.
0, 5, and 100 are all Whole Numbers as they're non-negative.

#### Integer Number

Every whole number is an Integer Number.
While 6 is both a Whole Number and an Integer Number, -6 is only an Integer Number.

#### Whole Number

Whole Numbers are a subset of Integer Numbers.
While 10 is both a Whole Number and an Integer Number, -10 is only an Integer Number.

#### Integer Number

Integer Numbers can represent values below and above zero.
-3 is an Integer Number below zero, while 3 is above zero.

#### Whole Number

Whole Numbers are non-negative numbers without fractions.
7 is a Whole Number because it's positive and doesn't have a fraction.

#### Integer Number

Integer Numbers span from negative infinity to positive infinity.
-1000 and 1000 are both distant Integer Numbers on the number line.

#### Whole Number

Whole Numbers exclude negative values.
15 is a Whole Number, while -15 isn't.
