🧮 JavaScript Numbers – Basics
All numbers in JavaScript are stored as floating point numbers (64-bit IEEE 754 format).

You can work with both integers and decimals.

let a = 10; // Integer
let b = 3.14; // Decimal (floating point)
let c = 2e3; // Exponential (2000)
let d = 0b1010; // Binary (10)
let e = 0xFF; // Hexadecimal (255)


🧪 Check Type or Validity

typeof 42 // "number"
isNaN("abc") // true
Number.isNaN("abc") // false
Number.isInteger(10) // true
Number.isFinite(5) // true


🧠 Math Object in JavaScript
JavaScript provides a built-in Math object with many helpful methods and constants.

✅ Math Constants

Constant: Math.PI
Value: 3.14159...
Description: The ratio of a circle's circumference to its diameter.


Constant: Math.E
Value: 2.718...
Description: Euler's number, the base of the natural logarithm.


Constant: Math.SQRT2
Value: ≈ 1.414
Description: The square root of 2.


Constant: Math.LN2
Value: ≈ 0.693
Description: The natural logarithm of 2.


Example:

console.log("The value of Pi is: " + Math.PI);
console.log("Euler's number is approximately: " + Math.E);
console.log("The square root of 2 is: " + Math.SQRT2);
console.log("The natural logarithm of 2 is: " + Math.LN2);


output:

The value of Pi is: 3.141592653589793
Euler's number is approximately: 2.718281828459045
The square root of 2 is: 1.4142135623730951
The natural logarithm of 2 is: 0.6931471805599453
