Hi, There's been recent discussion on the GNU APL forums about how to define the residue function on complex arguments. I wondered how it was specified in J, but the dictionnary page seems kind of vague.
Nuvoc says that (x|y)=y-x*<.y%x+0=x for all scalars x and y (including complex numbers). However, this is untrue for 'x y'=: 1j1 3j4 (tested on the old J for iOS) While it would seem like a logical extension, the dictionnary only says that this is true for rational numbers. So how is the residue of two complex numbers defined in J?
