- Added normal and exponential distributions to one of the examples.
- Improved the naming of a couple of local variables.
- Handled an error in the AccumulatingBucket ValueForIndex function whereby
the vestigal old behavior was accidentally preserved and not updated.
This could have been caught had the tests been updated first.
- Simplify Histogram prospectiveIndexForPercentile such that various
small tasks it performs are extracted into separate functions for easier
testing and code comprehension.
- Remedy a regression in Histogram prospectiveIndexForPercentile whereby
the prospective index may have included the terminating element of a
bucket.
- Provide help for Histogram prospectiveIndexForPercentile such that requesting
the terminating element of a bucket will fast-forward to the first element of
the next non-empty bucket.
- Fix TallingBucket's boundary constant, because they were originally keyed toward
percentages [0, 100], not decimal-based ones. The antique tests had been
temporarily commented out, which prevented this regression from being exposed.
