> In KolmogorovSmirnovTest.java the 2-sample Kolmogorov-Smirnov statistic is
> internally represented as double value. However, the KS-statistic can be
> accurately represented as long value if multiplied by both sample sizes. This
> approach saves some floating point operations and avoids difficulties when
> comparing two KS-statistics. Currently, Precision.compareTo with some
> tolerance must be used.
