JavaScript: Math SQRT2 property

This JavaScript tutorial explains how to use the math property called Math.SQRT2 with syntax and examples.

Description

In JavaScript, Math.SQRT2 is a math property that is used to return the square root of 2 which is the mathematical constant √2. Because Math.SQRT2 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.SQRT2 property is:

Math.SQRT2;

Parameters or Arguments

There are no parameters or arguments for the Math.SQRT2 property.

Returns

The Math.SQRT2 property returns the mathematical constant √2 which has an approximate value of 1.4142135623730951.

Note

  • The Math.SQRT2 property is a property of the Math object and not a math function. However, we have included the Math.SQRT2 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.SQRT2 property in JavaScript.

For example:

console.log(Math.SQRT2);

In this example, we have invoked the Math.SQRT2 property using the Math class.

We have written the output of the Math.SQRT2 property to the web browser console log, for demonstration purposes, to show what the Math.SQRT2 property returns.

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

1.4142135623730951

In this example, the Math.SQRT2 property returned a value of 1.4142135623730951 which is the value of the mathematical constant √2.
