Changes http://page.axiom-developer.org/zope/mathaction/47ComplexFormLogILogI/diff -- Dear William,
I think that the "usual sign convention" is a bad idea. 'myatan2(x,y)' should return unevaluated, since there is no way of knowing in which quadrant 'x+%i*y' is. That's why I proposed 'OrderedRing', in which case the answer is clear. We would have to think of the case of members of 'COMPLEX EXPR INT' where we happen to know the quadrant.
