Dear all, Just wondering if the correct defn of sin shouldn't be
sin=:1&o."0 instead of sin=:1&o. which has rank infinity. With the rank infinity definition +/@sin behaves just like +/@:sin But, ideally, +/@sin 4 5 should be a list of two numbers, while +/@:sin should be their sum. Just like, +/@*: and +/@:*: Thanks and regards, Arnab ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
