Given what we have to work with, it's a pretty good compromise; and it's
not hard to write either:
(%i2) atan2(sqrt(3)*x,x);
Is x positive, negative, or zero? pos;
(%o2) %pi/3
(%i3) atan2(sqrt(3)*x,x);
Is x positive, negative, or zero? neg;
(%o3) -(2*%pi)/3
(%i13) atan2(2008 * x,(1 + sqrt(5))*x);
Is x positive, negative, or zero? neg;
(%o13) atan(2008/(sqrt(5)+1))-%pi
