Mathematical Operations

Mathematical operations are fundamental in JavaScript for performing calculations and manipulating numerical data. JavaScript provides a built-in Math object with various methods and properties for carrying out mathematical operations. In this chapter, we'll explore mathematical operations from basic arithmetic to advanced mathematical functions, covering everything you need to know to perform mathematical tasks effectively in JavaScript.

Basic Arithmetic Operations

JavaScript supports basic arithmetic operations such as addition, subtraction, multiplication, and division.

Addition (+):

Adds two numbers together.

				
					const sum = 10 + 5;
console.log(sum); // Output: 15

Subtraction (-)

Subtracts one number from another.

				
					const difference = 10 - 5;
console.log(difference); // Output: 5

**Multiplication (*):**

Multiplies two numbers.

				
					const product = 10 * 5;
console.log(product); // Output: 50

Division (/):

Divides one number by another.

				
					const quotient = 10 / 5;
console.log(quotient); // Output: 2

Advanced Mathematical Functions

JavaScript’s Math object provides various advanced mathematical functions for more complex calculations.

Math.max():

Returns the largest of zero or more numbers.

				
					const largestNumber = Math.max(10, 20, 30);
console.log(largestNumber); // Output: 30

Math.min():

Returns the smallest of zero or more numbers.

				
					const smallestNumber = Math.min(10, 20, 30);
console.log(smallestNumber); // Output: 10

Math.sqrt():

Returns the square root of a number.

				
					const squareRoot = Math.sqrt(25);
console.log(squareRoot); // Output: 5

Math.pow():

Returns the base to the exponent power.

				
					const power = Math.pow(2, 3);
console.log(power); // Output: 8 (2 raised to the power of 3)

Constants and Properties

JavaScript’s Math object also provides various mathematical constants and properties.

Math.PI:

Represents the mathematical constant π (pi).

				
					console.log(Math.PI); // Output: 3.141592653589793

Math.E:

Represents the mathematical constant e, the base of natural logarithms.

				
					console.log(Math.E); // Output: 2.718281828459045

Mathematical operations are essential in JavaScript for performing calculations and manipulating numerical data.
