JavaScript: Math SQRT1_2 property

This JavaScript tutorial explains how to use the math property called Math.SQRT1_2 with syntax and examples.

Description

In JavaScript, Math.SQRT1_2 is a math property that is used to return the square root of 1/2 which is the mathematical constant 1/√2. Because Math.SQRT1_2 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.SQRT1_2 property is:

Math.SQRT1_2;

Parameters or Arguments

There are no parameters or arguments for the Math.SQRT1_2 property.

Returns

The Math.SQRT1_2 property returns the mathematical constant 1/√2 which has an approximate value of 0.7071067811865476. This is the reciprocal of the square root of 2.

Note

  • The Math.SQRT1_2 property is a property of the Math object and not a math function. However, we have included the Math.SQRT1_2 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.SQRT1_2 property in JavaScript.

For example:

console.log(Math.SQRT1_2);

In this example, we have invoked the Math.SQRT1_2 property using the Math class.

We have written the output of the Math.SQRT1_2 property to the web browser console log, for demonstration purposes, to show what the Math.SQRT1_2 property returns.

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

0.7071067811865476

In this example, the Math.SQRT1_2 property returned a value of 0.7071067811865476 which is the value of the mathematical constant 1/√2.
