Numbers in Javascript

In this video, we will discuss the Number data type in JavaScript. We will cover how to create numbers, the different types of numbers supported by JavaScript, and some of the methods available for the Number type.

Creating Numbers
There are two ways to create numbers in JavaScript:

- Number literals are simply sequences of numbers. For example, the following are all number literals:
- The Number constructor can be used to create numbers from other data types, such as strings. For example, the following code creates a number from a string:

Types of Numbers

The Number data type in JavaScript supports both floating point values (i.e. decimal numbers) and integers. For example, the following are both valid numbers in JavaScript:

- 23.4
- 100

Methods of the Number Data Type

Methods of the Number Data Type
There are a few methods available for the Number type in JavaScript. Some of the most commonly used methods are:

- toExponential(): This method can be used to format a Number into a string that represents the number in exponential notation.
- valueOf(): This method is used to get the number value stored inside a variable.
- isNan(): This function determines if the passed value is not a number (NaN).
- isFinite(): This function determines whether the value passed to it is finite or not.
- isInteger(): This function determines if the value passed to it is an integer.
