The complete guide to JavaScript Math Object with examples

Hello guys! morning to you all and welcome to my new tutorial post on JavaScript. In my last tutorial post, we rounded up our tutorial on Date Object. Now in this tutorial, we are going to be discussing about JavaScript Math Object.

The math object provides you with properties and methods for mathematical constants and functions. Unlike other global objects, Math is not a constructor. All the properties and  also the methods of Math are static and can be called by using Math as an object without even creating it.

Thus, you refer to the constant pi as Math.PI and you call the sine function as Math.sin(x), where x is the method's argument.


The syntaxes to call the properties and methods of a Math object are as follows -

var  pi_val = Math.PI;
var  sine_val = Math.sin(30);

Math Properties

Below is a list of all the properties of Math and their description.

Sr.No.Property & Description
1E \
Euler's constant and the base of natural logarithms, approximately 2.718.
Natural logarithm of 2, approximately 0.693.
Natural logarithm of 10, approximately 2.302.
Base 2 logarithm of E, approximately 1.442.
Base 10 logarithm of E, approximately 0.434.
Ratio of the circumference of a circle to its diameter, approximately 3.14159.
Square root of 1/2; equivalently, 1 over the square root of 2, approximately 0.707.
Square root of 2, approximately 1.414.
In the subsequent tutorials, we will be making use of few examples to demonstrate the usage of Math properties.

Math Methods

Below is a list of all the methods of Math object and their description

Sr.No.Method & Description
Returns the absolute value of a number.
Returns the arccosine (in radians) of a number.
Returns the arcsine (in radians) of a number.
Returns the arctangent (in radians) of a number.
Returns the arctangent of the quotient of its arguments.
Returns the smallest integer greater than or equal to a number.
Returns the cosine of a number.
Returns EN, where N is the argument, and E is Euler's constant, the base of the natural logarithm.
Returns the largest integer less than or equal to a number.
Returns the natural logarithm (base E) of a number.
Returns the largest of zero or more numbers.
Returns the smallest of zero or more numbers.
Returns base to the exponent power, that is, base exponent.
Returns a pseudo-random number between 0 and 1.
Returns the value of a number rounded to the nearest integer.
Returns the sine of a number.
Returns the square root of a number.
Returns the tangent of a number.
Returns the string "Math".
In the subsequent tutorials, we will be using few examples to demonstrate the proper usage of these methods associated with Math object.

Alright guys, we have come to the end of this tutorial post. In my next tutorial, i will use some examples to explain the proper usage of the Math properties.
