Numbers in JavaScript

JavaScript has several built-in data types to represent numbers. Here are some of the most common:

Integer: An integer is a whole number without decimals. In JavaScript, integers are represented using the Number data type.

Float: A float (or floating-point number) is a number with a decimal point. In JavaScript, floats are also represented using the Number data type.

NaN: NaN stands for "Not a Number". It is a special value in JavaScript that represents an undefined or unrepresentable value.

Infinity: Infinity is a special value in JavaScript that represents a number that is larger than any other number. It is often used to represent an overflow condition or an unbounded value.

Math Object: The Math object in JavaScript provides a set of mathematical functions that you can use to perform common operations, such as finding the square root, calculating the absolute value, or generating a random number.

Here is an example of using some of these features in JavaScript:

javascript

let a = 5;
let b = 2.5;
let c = NaN;
let d = Infinity;

console.log(a + b); // 7.5
console.log(a / 0); // Infinity
console.log(c + 10); // NaN
console.log(Math.sqrt(a)); // 2.23606797749979
console.log(Math.random()); // 0.7094905013301571
These are just some basic examples of how to work with numbers in JavaScript. There are many more features and functions available that you can use to perform complex mathematical operations and manipulate numbers in various ways.
