Name
Math — NN 2 IE J1 ECMA 1
Synopsis
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. Invoking a Math object
property or method adheres to the following syntax:
Math.propertyNameMath.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.
