Math Object

JavaScript provides several features to assist with solving mathematical problems.

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


Basic Constants for Mathematical Operations​

Math.PI returns the value of π (pi), which is the ratio of the circumference of a circle to its diameter.

Output the value of pi
console.log(Math.PI); // 3.141592653589793

Using Math.PI is useful when calculating the area or circumference of a circle.

Additionally, Math.E returns the value of the natural constant e.


Rounding​

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

Ceiling​

Math.ceil(number) rounds the number up to the nearest integer.

Math.ceil Ceiling
console.log(Math.ceil(4.2)); // 5

Flooring​

Math.floor(number) rounds the number down to the nearest integer.

Math.floor Flooring
console.log(Math.floor(4.7)); // 4

Maximum and 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

Exponents​

Math.pow(base, exponent) calculates the power of the base raised to the exponent.

Output Exponent Value
console.log(Math.pow(2, 3)); // 8 (2 raised to the power of 3)

Square Roots​

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)
