JavaScript Numbers
All JavaScript numbers are stored as decimal numbers (floating point).
Numbers can be written with, or without decimals:
Example :
<!DOCTYPE html>
<html>
<body>
<h2>JavaScript Numbers</h2>
<p>Numbers can be written with, or without decimals:</p>
<p id=”demo”></p>
<script>
let x1 = 34.00;
let x2 = 34;
let x3 = 3.14;
document.getElementById(“demo”).innerHTML =
x1 + “<br>” + x2 + “<br>” + x3;
</script>
</body>
</html>
Output

Description :
In JavaScript, numbers are a single data type used to represent both integers (like 100, -5) and floating-point (decimal) numbers (like 3.14, 0.5). Unlike many other programming languages, JavaScript does not have separate types for integers and decimals—all numbers are treated as floating-point (64-bit IEEE 754 format) under the hood.
