When I first learned to program (in COBOL) I was taught as a rule of thumb
that complex COMPUTE statements should wherever possible be laid out so that
the multiplications are performed before the divisions in order to avoid
this loss of precision.

Hi Buck,  Its the divide '/' operation thats the LULU.
It creates a intermed result of 30,20 or something equally wierd.
Then any sebsequent mults, divs ect. overflow the precision and the rules
drop back to 1 dec place.  U got no divides in your example.
