# Math Object Overview

The Math object allows JavaScript to perform mathematical tasks.

The Math object does not have a constructor. All properties/methods of Math can be called by using Math as an object, without creating it.

The following examples show various ways to use the Math object:

``````// Returns PI
var x = Math.PI;

// Returns the square root of 16
var y = Math.sqrt(16);``````

## Properties

Property Description
`E` Returns Euler's number (approx. 2.718)
`LN2` Returns the natural logarithm of 2 (approx. 0.693)
`LN10` Returns the natural logarithm of 10 (approx. 2.302)
`LOG2E` Returns the base-2 logarithm of E (approx. 1.442)
`LOG10E` Returns the base-10 logarithm of E (approx. 0.434)
`PI` Returns PI (approx. 3.14159)
`SQRT1_2` Returns the square root of 1/2 (approx. 0.707)
