JavaScript Number valueOf( ) Method Last Updated : 22 May, 2023 Comments Improve Suggest changes Like Article Like Report JavaScript Number valueOf( ) method in JavaScript is used to return the primitive value of a number. This method is usually called internally by JavaScript and not explicitly in web code Syntax: number.valueOf() Parameters: This method does not accept any parameter. Return Value: The valueof() method in JavaScript returns a number representing the primitive value of the specified Number object. Below are examples of the Number valueOf( ) Method: Example 1: In this example, the output comes out to be NaN as the value stored in the variable is NaN. JavaScript let num=NaN; console.log(num.valueOf()); Output: NaN Example 2: Passing a positive number as an argument in the valueOf() method. JavaScript let num=213; console.log(num.valueOf()); Output: 213 Example 3: Passing a negative number as an argument in the valueOf() method. JavaScript let num=-213; console.log(num.valueOf()); Output: -213 Example 4: Passing zero as an argument in the valueOf() method. JavaScript let num=0; console.log(num.valueOf()); Output: 0 Example 5: Passing an equation(equating to infinite value) as an argument in the valueOf() method. JavaScript let num=0/0; console.log(num.valueOf()); Output: Nan Supported Browsers: GoogleEdgeFirefox Apple Safari Opera We have a complete list of Javascript Number Objects methods, to check those please go through this Javascript Number Complete reference article.

This constant has a value of (253 - 1). Here safe refers to the ability to represent integers and to compare them. Syntax: Number.MAX_SAFE_INTEGER Return Value: A constant number.

This constant has a value of (-(253 - 1)). Use Number.MIN_SAFE_INTEGER, as a property of a number object because it is a static property of a number. Syntax: Number.MIN_SAFE_INTEGER Return Value: Co 1 min read JavaScript NaN Property NaN, which stands for "Not a Number," is a special value in JavaScript that shows up when a mathematical operation can't return a valid number. This can happen if you try something like dividing zero by zero or converting a string that doesn't contain numbers.

It can be explained as a number that is lower than any other number. It is a Read-Only property.
