distinguish certain types of data
from others, this way a programming language can be more useful to
authors. Variables created can hold any data type, and they are
processed according to the data type we define. Every good programming
language distinguishes data types when scripts run.
Here is a breakdown of the ActionScript 3.0 Data Types:
||Can hold only two possible values, true
or false. If the value is not initialized it
defaults to false.
||Use for numbers. If you do not require a
floating point number(decimal), use the int type for working with
numbers in youe application. The default value for variables that are
of the data type int is 0.
||Used to signify that a pointer
intentionally does not point to (or refer to) an object. The Null data
type contains only one value, null.
||Used for integers, unsigned integers, and
floating-point numbers. To store a floating-point number, include a
decimal point in the number. If your number has no decimal point, the
number will be seen as an integer.
||Represents a sequence of alphanumeric
characters and symbols. For instance, "abc" is a string, as well as
"abc123". This email address is also a string "email@example.com".
||Use the uint data type for special
circumstances that call for non-negative integers. Has a value range
from 0 to 4,294,967,295. The uint data type has an internal sign bit
that is most appropriate for handling color values. For integer values
larger than the maximum uint value, use the Number data type.
||Contains only one value, undefined.
||The base class for all class definitions
in ActionScript. The ActionScript 3.0 version of the Object data type
differs from that of previous versions in three ways. Default value
for instances of the Object class is null.
