Another clue, it has been argued, is provided by the given value itself, because round numbers are likely to be interpreted as approximations (Krifka 2002).
in "a quarter of papers were marked A" the given value is a simple fraction, suggesting that V G has been selected by the writer as a round number conveniently near V A , and that the relationship is accordingly The term hedge was introduced by Lakoff (1973) and subsequently applied to numerical descriptions by Dubois (1987), who studied imprecision in oral scientific presentations and listed some common numerical hedges (e.g., "about", "almost", "nearly", "of the order of", "a little over"); Crystal (1988) added a few more.
