Sorry, you are of course correct where integers are concerned. I was
looking at it simplisticly as a maths equation, and should have read
Stephen's post more carefully. Then I would have realised he meant:

((2^31) * 4) / 32  (possibly!)

Sorry again - I was actually thinking of precedence, but my fingers
got to the keys before my brain found the word :-)

My original idea still stands though - if you use parentheses
correctly the equation will be evaluated as you intend, not as the
compiler sees fit.
