Integer numbers are whole numbers that can be positive or negative but do not have fractions or decimals.

You can use the term “integer” to describe a whole number. It means a number without a fraction or a decimal.

Unlike whole numbers, integer numbers refer to negative numbers and positive amounts.

Is 0 an integer number?

However, different people define integers in different ways. For example, some people would argue that negative numbers are integer numbers, whereas others would claim that even 0 is not an integer.

Usually, though, 0 is an integer, as are 109, 7, -3, 8, and -28. But, again, these are whole numbers with no fractions or decimals.

Examples of numbers that aren’t integers are 0.7, 1/3, -10.56, pi, and root 3. Again, it is because they are not whole numbers.

So there are three types of integers:

  • Positive numbers
  • Negative numbers
  • Zero

What are integers used for in everyday life?

Common sense sometimes tells you you need an integer to find the answer to a question. For example, if you’re painting a wall and need 2.3 tins to cover it, you’ll have to buy three tins. You can’t buy 0.3 tins of paint to get the exact amount you need. Sometimes, you have to round up to an integer.

However, you’ll see integers used everywhere in daily life. Everything from the calendar to the binary code uses integers to represent information.

That’s why getting a good understanding of them at a young age is so essential.
