Javascript Math Objects - Properties and Methods
Description
JavaScript math object is a top-level, a predefined object for mathematical constants and functions.
Can not be created by the user. It is a predefined object
Mathematical properties and functions can be calculated by math.property or math.method (for example math.abs(4.568)).
