JavaScript: Number.MIN_VALUE property

This JavaScript tutorial explains how to use the Number property called MIN_VALUE with syntax and examples.

Description

In JavaScript, MIN_VALUE is a static property of the Number object that is used to return the smallest positive numeric value that is approaching 0. It does not return a negative value. Because MIN_VALUE is a property of the Number object, it must be invoked through the object called Number.

Syntax

In JavaScript, the syntax for the MIN_VALUE property is:

Number.MIN_VALUE;

Parameters or Arguments

There are no parameters or arguments for the MIN_VALUE property.

Returns

The MIN_VALUE property returns the minimum positive value that can be represented in JavaScript which is 5e-324. (ie: smallest positive numeric value approaching 0).

Note

  • Any value that is lower than MIN_VALUE will be converted to 0 by JavaScript.
  • The MIN_VALUE property is a property of the Number object and not a number function. However, we have included the MIN_VALUE property within our JS Number Methods section because you will most likely use this property in conjunction with the Number methods found in this section.

Example

Let's take a look at an example of how to use the MIN_VALUE property in JavaScript.

For example:

console.log(Number.MIN_VALUE);

In this example, we have invoked the MIN_VALUE property using the Number class.

We have written the output of the MIN_VALUE property to the web browser console log, for demonstration purposes, to show what the MIN_VALUE property returns.

The following will be output to the web browser console log:

5e-324

In this example, the MIN_VALUE property returned a value of 5e-324 which represents the smallest positive numeric value (approaching 0) that can be represented in JavaScript.
