> 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.
