The expression 3 +&.^.4 stands for Antilog (log 3) + (log 4) Irrespective of the rank of antilog it is applied only once because both arguments are a single number.
I think Raoul is right - something isn't working properly when the rank conjunction is used to assign zero rank to the C verb. 10 ;&.(C"0 1) 20 A-y A-y B-y +---+-----------------+ |B-y|+--------+---+--+| | ||+---+--+|A-y|20|| | |||A-y|10|| | || | ||+---+--+| | || | |+--------+---+--+| +---+-----------------+ 10 ;&.(C"1 0) 20 A-y A-y B-y B-y B-y +---+----------+ |B-y|+--------+| | ||+---+--+|| | |||A-y|10||| | ||+---+--+|| | |+--------+| +---+----------+ |B-y|+---+ | | ||A-y| | | |+---+ | +---+----------+ ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
