Concept

Math is a built-in object in Javascript, used to support complex operations during runtime.

Basic operations

The Math object in Javascript provides methods to perform basic operations such as addition, subtraction, multiplication, division, and modulo. Here are some examples:

Addition:

var sum = Math.add(2, 3);
console.log(sum); // 5

Subtraction:

var difference = Math.subtract(5, 3);
console.log(difference); // 2

Multiplication:

var product = Math.multiply(4, 5);
console.log(product); // 20

Division:

var quotient = Math.divide(10, 2);
console.log(quotient); // 5

Modulus:

var remainder = Math.modulo(10, 3);
console.log(remainder); // 1

Arithmetic operations

The Math object provides methods to perform mathematical operations such as square root, exponentiation, and rounding numbers. Here are some examples:

Square root:

var squareRoot = Math.sqrt(25);
console.log(squareRoot); // 5

Exponentiation:

var power = Math.pow(2, 3);
console.log(power); // 8

Rounding numbers:

var roundedNumber = Math.round(3.7);
console.log(roundedNumber); // 4

Mathematical constants

The Math object provides mathematical constants such as pi (π), e, and constants related to logarithms.

Pi constant:

var pi = Math.PI;
console.log(pi); // 3.141592653589793

Constant e:

var e = Math.E;
console.log(e); // 2.718281828459045

Natural logarithm constant:

var naturalLogarithm = Math.LN10;
console.log(naturalLogarithm); // 2.302585092994046

Using other methods of the Math object

In addition to the mentioned operations and constants, the Math object also provides many other useful methods such as:

Find absolute value:

var absoluteValue = Math.abs(-5);
console.log(absoluteValue); // 5

Find the maximum or minimum value in a list of numbers:

var maxNumber = Math.max(1, 2, 3, 4, 5);
console.log(maxNumber); // 5

var minNumber = Math.min(1, 2, 3, 4, 5);
console.log(minNumber); // 1

Sin, cos and tan:

var sineValue = Math.sin(0);
console.log(sineValue); // 0

var cosineValue = Math.cos(Math.PI);
console.log(cosineValue); // -1

var tangentValue = Math.tan(Math.PI / 4);
console.log(tangentValue); // 1
