public class Number
extends Object

The Number class is a simple wrapper object for the Number data type. You can manipulate primitive numeric values by using the methods and properties associated with the Number class. This class is identical to the JavaScript Number class.

The properties of the Number class are static, which means you do not need an object to use them, so you do not need to use the constructor.

The following example calls the toString() method of the Number class, which returns the string 1234:

var myNumber:Number = new Number(1234);
myNumber.toString();

The following example assigns the value of the MIN_VALUE property to a variable declared without the use of the constructor:

var smallest:Number = Number.MIN_VALUE;

Availability: ActionScript 1.0; Flash Player 5 - (became a native object in Flash Player 6, which improved performance significantly).

Property summary

`static`	MAX_VALUE`:Number`	The largest representable number (double-precision IEEE-754).
`static`	MIN_VALUE`:Number`	The smallest representable number (double-precision IEEE-754).
`static`	NaN`:Number`	The IEEE-754 value representing Not A Number (`NaN`).
`static`	NEGATIVE_INFINITY`:Number`	Specifies the IEEE-754 value representing negative infinity.
`static`	POSITIVE_INFINITY`:Number`	Specifies the IEEE-754 value representing positive infinity.

var aaa:Number = Number(81.9);
var bbb:Number = Number(81.7);
var ccc:Number = aaa - bbb;

trace(ccc);

the result is 0.200000000000003

i want that result is 0.2

I have the same issue as above --
How do you set the precision of a Number?

Thanks in advance,
