Hi A good idea, weak zero would be -0 and +0 of limit calculus. The idea does have the 'problem' of no strong infinity. This is because such an infinity would not have a sign (a loop sign from %0). Nice paper by Wirth :-)
The general subject of summation series and anulus of convergence is interesting to me.It would appear that outside the anulus, some sign reversal happens preventing the series from converging to the strong equality perfection. This suggests something along the lines of a taylor series with ! (gamma) having a complex character with possible solution of the root for convergence. The generalized gamma/pochammer also produces the logarithm (d^:_1 (%x)) I am wonder if anyone has worked on a general notation/solution to the representation of multiple complex values. cheers jacko ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
