What Is Integer Data Type With Example?

Integer is a fundamental data type in programming that represents whole numbers without any fractional or decimal part. It is used to store and manipulate numeric values that do not require precision beyond the decimal point. In HTML, integer data type can be represented using the number input type or by using JavaScript to handle calculations involving integers.

Example:

Let’s take a simple example to understand how integer data type works in HTML. Suppose we have a form where users can enter their age:

In the above example, the input field with the number type restricts the user to enter only integer values. If the user tries to enter a decimal number, an error message will be displayed.

Integer Operations:

Integers can be used in various mathematical operations such as addition, subtraction, multiplication, and division. Let’s see some examples:

• Addition:

To add two integers together, use the plus (+) operator:

<script>
    var num1 = 10;
    var num2 = 5;
    var sum = num1 + num2;
    console.log(sum); // Output: 15
</script>

• Subtraction:

To subtract one integer from another, use the minus (-) operator:

<script>
  var num1 = 10;
  var num2 = 5;
  var difference = num1 - num2;
  console.log(difference); // Output: 5
</script>

• Multiplication:

To multiply two integers together, use the asterisk (*) operator:

<script>
  var num1 = 10;
  var num2 = 5;
  var product = num1 * num2;
  console.log(product); // Output: 50
</script>

• Division:

To divide one integer by another, use the forward slash (/) operator:

<script>
  var num1 = 10;
  var num2 = 5;
  var quotient = num1 / num2;
   console.log(quotient); // Output: 2
</script>

Conclusion:

In HTML, the integer data type is represented using the number input type. It allows users to enter whole numbers and perform various mathematical operations on them using JavaScript. Understanding how to work with integers is essential for building interactive and dynamic web applications.
