Comment #11 on issue 1467 by smichr: sorting values with imaginary numbers in radical http://code.google.com/p/sympy/issues/detail?id=1467
Ted, regarding the underlying issues: I.is_comparable is False because I derives from Atom, not NumberSymbol. If you change it to be comparable then tests like bool(3<I) lead to infinite recursion. sqrt(I).is_comparable is True because it is not represented as a complex number (I think), it is a negative base raised to a power so maybe that't the difference: >>> sqrt(I) (-1)**(1/4) I'm not saying these aren't still issues, I'm just trying to document the reasons they are as they are. /c -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
