I remember that years ago there was a verb to divide 0 by 0 and produce _, but I cannot find it anywhere. It was probably not the one I have produced tonight, but here it is, anyhow.
div =: 0:`%@.(+.&*) 0 1 2 3 3 _6 div 0 1 _5 6 0 0 0 1 _0.4 0.5 _ __ -- (B=) ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
