Another way to tackle it as well is to split it and compare the 2nd element of the split array.
var num:Number = 2.3; var split:Array = String(num).split("."); trace(3 == split[1]); On 12/6/06, [EMAIL PROTECTED] < [EMAIL PROTECTED]> wrote:

To: "Flashcoders mailing list" <flashcoders@chattyfig.figleaf.com> Message-ID: <[EMAIL PROTECTED]> Content-Type: text/plain; charset=UTF-8; format=flowed In Flash 9, I get this for the traces: 2.3 0.2999999999999998 0.3 false false true Good old-fashioned floating point precision error. Instead of testing if they are equal, You could test if the difference between them is very small, e.g.: trace(Math.abs(num2 - num3) < 0.00001); // true On 12/6/06, Doug Coning <[EMAIL PROTECTED]> wrote: > I'm scratching my head over this.
