Javascript - How to get an error if typing int instead of float?

Basically what I want to do is make sure that if I pass a int into a function that requires a float, I will get an error. So something like this, should give me an error saying it's missing an argument.

 function AddAction(selectedText : String, selectedFloat : float) {
   //whatever
 }
 
 var selectedInt: int = 3;
 
 //This should not work:
 AddAction("Wait", selectedInt);

(Please don't tell me C# is much better, etc. I know it but it's not an option atm).

Try this?

selectedAction : function(), time : int

Unless time has to be a float...

Not sure what you wrote does? I just want to make sure that if I type a int I will get an error saying that function requires a float. (Also clarified the question, hopefully its more clear now)

Ah, oops, sorry, what was I thinking...

How about calling this function in AddAction()?

 IsItAnInt(time);
 
 
 function IsItAnInt(float num)
 {
    int i = Mathf.FloorToInt(num : float);
    if (num != float(i) )
       Debug.LogError("You entered an integer.");
 }
