            The quantile functions for these distributions are hard to specify in
            a manner that will satisfy everyone all of the time. The default behaviour
            is to return an integer result, that has been rounded <span class="emphasis"><em>outwards</em></span>:
            that is to say, lower quantiles - where the probability is less than
            0.5 are rounded down, while upper quantiles - where the probability is
            greater than 0.5 - a
