I wish to use the max function on absolute values, but carry the sign
of the original values. That is:

a=max(abs(a1),abs(a2)) ! but a has sign of either a1 or a2

I'm doing this with an IF statement now but wonder if there isn't some
combination of max and sign that will give the same result without an
IF statement.
