There is a method of the Number object in JavaScript that allows us to set a fixed decimal point on a number and then return it as a string. This article will talk about the syntax of this method and show you how to use it.
When we talk about primitives in JavaScript, we are talking about elements that are not objects and to which no method is associated. When we want to take a primitive value and make it an object, we can do it with primitive envelopes which can bypass the value or the data type.
Numbers have a primitive wrapper object. We use it to transform the string representations of a number into an actual Number object with methods we can apply on it.
For example, let’s say we have a string representation of a number because we have a form that requires the user to enter a numeric value for a field on the screen . We can take this input, turn it into a number, and then use any number of methods to work with that value.
Here we have used the toFixed () method of the Number object to make the number the desired length. The syntax of the method is as follows:
If you are dealing with forms, there is one thing you should remember: these values ​​come in the form of strings. So, to use the toFixed ()
method on them, you need to turn them into numeric representations.
