Hi J, After
z =: 281474976711954 compare <.z%32 8796093022249 and z <.@:% 32 8796093022248 The second is "more correct", because: 17j3 ": z%32 8796093022248.562 Unfortunately I had been using the first (and odd or even mattered a lot). Is it a bug in J, or is it something I should have been aware of?
