Name
Number( ) Global Function — convert a value to the Number datatype
Availability
Flash 5
Synopsis
Number(value)
Arguments
- value
An expression containing the value to be converted to a number.
Returns
The result of converting value to a
primitive number.
Description
The Number( ) function converts its argument to
a primitive numeric value and returns that converted value. The
results of converting various types of data to a primitive number are
described in Table 3.1. It’s often not
necessary to use the Number( ) function;
ActionScript automatically converts values to the
number type when appropriate.
Be sure not to confuse the global Number( )
function with the Number class constructor. The
former is a function that converts a value to the
number type, whereas the latter is the class
used to wrap a primitive numeric datum in an object that can take
properties and methods.
Usage
Note that the Number( ) function frequently
appears in Flash 4 .fla files that have been
converted to the Flash 5 format. For information on how datatypes are
handled when Flash 4 files are converted to Flash 5, see Section 3.4.4 in Chapter 3.
