Working with Numbers (toFixed)

Ah, the joy of finding a simple method to make life easier.

Now I have always wanted the Ability to get just a few numbers from a number like 3.14567545645. I knew there must be a way to do this and now I just found it.

function toFixed(fractionDigits:uint):String

So You can do the following:

he following example shows how toFixed(3) returns a string that rounds to three decimal places.

var num:Number = 7.31343;
trace(num.toFixed(3)); // 7.313


The following example shows how toFixed(2) returns a string that adds trailing zeroes.

var num:Number = 4;
trace(num.toFixed(2)); // 4.00
