round =: 1&$: : (dyad def '<.@:(1r2+])&.:(%&x) y') assert 1 -: round 1.2 assert 1.25 -: 0.25 round 1.2
Round =: adverb def '<.@:(1r2+])&.:(%&m) y' Is there a tacit definition of round using under? What is the tacit definition of adverb Round? Thanks, Dave. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
