What is Math Object in JavaScript Program?

Javascript Web Development Front End Technology

Math is an inbuilt object provided by JavaScript that has multiple attributes and methods for different mathematical functions and constants. This is not a function object.

Maths objects generally work with the Number type.
The Math object does not have a constructor and all the properties and methods are fixed or static.
The cosine function is also known as Math.cos(y). Similarly, the pi constant is known as Math.PI.

All the properties or methods provided by the Math object are static and can be called by using the Math as an object without actually creating it. In this article, we will explore different available methods and properties that are used in JavaScript.

Some static Math properties are listed below −

Property	Description	Return value
Math.E	This represents the Euler’s constant. Its default value is 2.718 approximately.	Euler’s number
Math.LN2	This represents the natural log which has an approx value of 0.693147180.	Natural Log of 2
Math.LN10	This represents the natural log with Base 10 which has an approx value of 2.302585.	Natural Log of 10
Math.LOG2E	This represent Base-2 log of E with approx value of 1.442695.	Base 2 Log of E
Math.LOG10E	This represent Base-10 log of E with approx value of 0.43429844	Base 10 Log of E
Math.PI	This represents the ratio of the circumference of a circle to its diameter i.e. 3.14159.	PI value
Math.SQRT1_2	This represents the square root of 1/2 with approx value of 0.70710678.	The square root of 1/2
Math.SQRT2	This represents square root of 2 which is 1.41421356 approximately	The square root of 2

Example 1

In the example below, we apply different static Math properties.

Static Math Methods: Math objects have static methods associated with them. Some of the methods are described below.

Sr.No	Methods & Description
1	Math.abs(y) This returns the positive value of y
2	Math.acos(y) This returns the acos value of y
3	Math.acosh(y) Returns hyperbolic a-cosine value of y
4	Math.asin(y) Returns arcsine value of y
5	Math.asinh(y) Returns hyperbolic arcsine value of y
6	Math.atan(y) Returns arctangent value of y
7	Math.atanh(y) Returns hyperbolic arctangent value of y
8	Math.atan2(y, x) Returns arctangent of the quotient of its arguments
9	Math.cbrt(y) Returns the cube root of y.
10	Math.ceil(y) Returns the smallest integer greater than or equal to y.
11	Math.clz32(y) Returns the number of leading zero bits of the 32-bit integer y.
12	Math.cos(y) Returns the cosine of the angle y.

Example 2

In the below example we apply different Math methods such as ceil, floor, round, sin, cos, min, max, etc.
