Christian Winter commented on MATH-699:
---------------------------------------

Yes, we can get rid of {{IntegerDistribution.getDomainLowerBound(double)}} and {{IntegerDistribution.getDomainUpperBound(double)}}. I will do this in the reimplementation of {{IntegerDistribution.inverseCumulativeProbability(double)}} based on MATH-692.
                
> inverseCumulativeDistribution fails with cumulative distribution having a plateau

> This bug report follows MATH-692. The attached unit test fails. As required by the definition in MATH-692, the lower-bound of the interval on which the cdf is constant should be returned. This is not so at the moment.
