> The algorithm tries to merge the two nearest points in the histogram and
> create a new point that is in between the two merged points based on the
> weight of each point. This can overflow long arithmetic with the code that is
> currently there and the work around is pick one of the points and just put
> it there.
> This can be worked around by changing the midpoint calculation to not
> overflow.
