JavaScript: Math.LN2 property

This JavaScript tutorial explains how to use the math property called Math.LN2 with syntax and examples.

Description

In JavaScript, Math.LN2 is a math property that is used to return the mathematical constant loge2 which is the natural logarithm of 2. Because Math.LN2 is a property of the Math object, it must be invoked through the placeholder object called Math.

Syntax

In JavaScript, the syntax for the Math.LN2 property is:

Math.LN2;

Parameters or Arguments

There are no parameters or arguments for the Math.LN2 property.

Returns

The Math.LN2 property returns the mathematical constant loge2 which has an approximate value of 0.6931471805599453.

Note

  • The Math.LN2 property is a property of the Math object and not a math function. However, we have included the Math.LN2 property within our JS Math Functions section because you will most likely use this property in conjunction with the Math functions found in this section.

Example

Let's take a look at an example of how to use the Math.LN2 property in JavaScript.

For example:

console.log(Math.LN2);

In this example, we have invoked the Math.LN2 property using the Math class.

We have written the output of the Math.LN2 property to the web browser console log, for demonstration purposes, to show what the Math.LN2 property returns.

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

0.6931471805599453

In this example, the Math.LN2 property returned a value of 0.6931471805599453 which is the value of the mathematical constant loge2. This is the value of the natural logarithm of 2.
