Math Object

JavaScript offers various functionalities to help solve mathematical problems.

The Math object provides various methods and constants to help with mathematical operations.


Basic Constants​

  • Math.PI: Returns the value of π (Pi), which is the ratio of a circle's circumference to its diameter.
Output the value of Pi
console.log(Math.PI); // 3.141592653589793

Using Math.PI, you can easily calculate the area or circumference of a circle.


Rounding, Ceiling, Flooring​

  • Math.round(number): Rounds the number to the nearest integer.
Math.round Rounding
console.log(Math.round(4.7)); // 5
console.log(Math.round(4.4)); // 4

  • Math.ceil(number): Rounds the number up to the nearest integer.
Math.ceil Ceiling
console.log(Math.ceil(4.2)); // 5

  • Math.floor(number): Rounds the number down to the nearest integer.
Math.floor Flooring
console.log(Math.floor(4.7)); // 4

Maximum, Minimum Values​

  • Math.max(number1, number2, ...): Returns the largest of the given numbers.

  • Math.min(number1, number2, ...): Returns the smallest of the given numbers.

Output maximum and minimum values
console.log(Math.max(3, 7, 2, 8, 5)); // 8
console.log(Math.min(3, 7, 2, 8, 5)); // 2

Power, Square Root​

  • Math.pow(base, exponent): Returns the base to the exponent power.
Output power value
console.log(Math.pow(2, 3)); // 8 (2 raised to the power of 3)

  • Math.sqrt(number): Returns the square root of the given number.
Output square root value
console.log(Math.sqrt(16)); // 4 (square root of 16)
