Math Object

The Math object enables you to perform scientific tasks.

Math isn't a constructor. All properties/techniques for Math can be called by utilizing Math as an article, without making it.

Syntax

var x = Math.PI;           /Returns PI
var y = Math.sqrt(16);     /Returns the square foundation of 16

Math Object Properties
