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
