Well, it turns out that doesn't work either if the int is positive. If an int is positive all of the follow tests return true:
var testInt:int = 5; var obj:Object = testInt; obj is int -> true obj is uint -> true obj is Number -> true Sooooo, I'm back to assuming there is no way to tell an int from a uint. --- In [email protected], "Paul Whitelock" <[EMAIL PROTECTED]> wrote: > > I found another way that seems to work (not sure why though): > > var testUint:uint = 1; > var testInt:int = -1; > var testNumber:Number = 1.1; > > var obj:Object = testUint; > > trace ("uint: " + (obj is uint && obj is int)); > trace ("int: " + (obj is int && !(obj is uint))); > trace ("Number: " + ((obj is Number) && !(obj is int) && !(obj is uint))); > > Output: > uint: true > int: false > Number: false > > obj = testInt; > > trace ("uint: " + (obj is uint && obj is int)); > trace ("int: " + (obj is int && !(obj is uint))); > trace ("Number: " + ((obj is Number) && !(obj is int) && !(obj is uint))); > > Output: > > uint: false > int: true > Number: false > > obj = testNumber; > > trace ("uint: " + (obj is uint && obj is int)); > trace ("int: " + (obj is int && !(obj is uint))); > trace ("Number: " + ((obj is Number) && !(obj is int) && !(obj is uint))); > > Output: > uint: false > int: false > Number: true > > > --- In [email protected], "Paul Whitelock" <paul@> wrote: > > > > Thanks! That did help, but it doesn't seem to work for a uint.
