	Some compiled functions yield reals even if the input and necessary output are integers.  How can I force the output to be an integer rather than a real in such cases?  To be clear, not all compiled program output produces reals; some compiled programs, given integer inputs, produce integer outputs.  But some do not.  An example is:

collatz = Compile[{{n, _Integer}}, If[EvenQ[n], n/2, 3 n + 1]]

It produces real rather than integer output, and I'd like to force integer output if possible.

	Thanks

	Best,

	Harvey
