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
