Chapter 4. Primitive Datatypes
Primitive
data
consists of simple characters or keywords such as the numbers 0, 1,
2, 3, 4, 5, 6, 7, 8, 9, or the strings "a",
"b", "c". As we learned in the previous
chapter, the primitive datatypes supported by ActionScript are
number, string,
boolean, undefined, and
null. In this chapter we'll learn how to
define, examine, and change data of each type.
4.1. The Number Type
Numbers are used for counting, mathematics, and
to keep track of numeric properties in our movies (like the current
frame of a movie clip or its location on the Stage). Let's see
how numbers are defined and manipulated in ActionScript.
