You would of course have to be careful with that, because it could give imprecise results. For example, a=: ,1e50 b=: ,3 c=: ,1 c} a,:b 3 a+c*b-a 0 If you want a solution with arithmetic operations (which admittedly is convenient in some more complicated expressions), you could try this: (a*-.c)+b*c 1 20 3 -- Ambrus ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
