Doesn't work that way for me -- mine returns the original number. In
particular, the json datatype doesn't do any parsing at all, so it "cannot
happen". jsonb does parsing, but that one also doesn't round it off.

Are you doing this from psql or some other frontend tool? My guess is the
frontend tool is somehow messing with the data for you. If you didn't
already do it in psql, please confirm if you can reproduce it from there.
