>          Components: core/search
>    Affects Versions: 5.0
>            Reporter: Tim Allison
>            Priority: Trivial

> 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.
