Coding challenge: FizzBuzz

Here's my entry:

For Local i:Int = 1 To 100
	Local div35:Int = 0
	If isInt(i / 3.0) Then div35 :+ 1
	If isInt(i / 5.0) Then div35 :+ 2
	Select div35
		Case 1 
			Print "Fizz"
		Case 2
			Print "Buzz"
		Case 3
			Print "FizzBuzz"
		Default
			Print i
	End Select
Next

Function isInt:Int(num:Float)
	If num = Int(num) Return True Else Return False
End Function
