I think they mean data types: fixed point (e.g. int) vs floating point (double). Research has been pushing that way. I don’t see what it has to do with adjointness other than maybe that a fixed point variable separates mathematically-defined space more reliably than a floating point variable. I don’t see what either really has to do with this post. Fixed point variables do not require not using feedback loops.
