True, they are necessary, but they are not sufficient.  If you want
ROUND to do what its name implies (for nonnegative arguments), you
should have written it
	#define	ROUND(real)		((long)(.5 + (real)))
since unary operators (including cast) have precedence over addition.
Just thought I should point that out, since you were otherwise being
quite careful with parens.
