The Math object is used only in its static object form as a library of math constant values and (mostly trigonometric) operations. As a result, there is no constructor function. Math object properties are constant values, while methods return a numeric value reflecting some math operation on a value; the original value is not altered when the method is invoked.

Invoking a Math object property or method adheres to the following syntax:

Math.propertyName
Math.method(param1[, param2])

Be sure to observe the uppercase "M" in the Math object in script statements. All expressions involving the Math object evaluate to or return a value.
