[jira] [Created] (LUCENE-5469) Add small rounding to FuzzyQuery.floatToEdits

Tim Allison created LUCENE-5469:
-----------------------------------

             Summary: Add small rounding to FuzzyQuery.floatToEdits
                 Key: LUCENE-5469
                 URL: https://issues.apache.org/jira/browse/LUCENE-5469
             Project: Lucene - Core
          Issue Type: Bug
          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"
