Is Sage's unsigned_infinity intended to model complex infinity? >> > > What else would it be? >
Well, you can compactify a line - into a segment by adding two points (-oo, +oo), - into a circle by adding one point (oo). Think of slopes of lines through the origin in the plane RR^2; the vertical line has slope oo. To me, unsigned_infinity could refer to that, and could be unrelated to complex infinity. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
