A biv is what we'd call a bit. It comes from, in "bivalent choices, as in a logic machine", as Professor Dana said in Academic Discourse. The notion of a logic machine, aggregating all the combinations of a number of bivalent choices (we would say binary or boolean IOW, a North American might say DeMorgan) is well established in Mexican culture. Mercator himself referred to it in I, Mercator (Part 3).
