Robert Muir commented on LUCENE-5469:
-------------------------------------
We deprecated this stuff already in 4.x, and issued warnings (e.g. in the
queryparser syntax) that such syntax was deprecated in 4.x and will be removed
in 5. We should nuke this stuff!
> Add small rounding to FuzzyQuery.floatToEdits

> Project: Lucene - Core
> Issue Type: Bug
> Components: core/search
> Affects Versions: 5.0

> Priority: Trivial
> Labels: easyfix

> I realize that FuzzyQuery.floatToEdits is deprecated, but I'd like to make a
> small fix for posterity. Because of floating point issues, if a percentage
> leads to a number that is very close to a whole number of edits, our cast to
> int can improperly cause misses.
> ddddd~0.8 will not match "ddddX"
> eeeee~0.8 will not match "eeee" or "eeeeee"
> This is a trivial part of the plan to reduce code duplication with
> LUCENE-5205.
