Subject [jira] [Commented] (TEXT-76) Jaro Winkler implementation introduced in 3.5 is not correct
Date Wed, 05 Apr 2017 10:02:41 GMT

    [ https://issues.apache.org/jira/browse/TEXT-76?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15956612#comment-15956612

Bruno P. Kinoshita commented on TEXT-76:
----------------------------------------

Issue moved to Commons Text. Confirmed issue with JaroWinkler in Commons Lang latest, as well
as in Commons Text latest versions.

The problem is the Math.round, that rounds a very long 0.99... double number into 100 long.
Then divides by 100D.

> Using 3.5 commons-lang the following call return a distance of 1
> StringUtils.getJaroWinklerDistance(“/opt/software1”,  “/opt/software2”)
> Jaro Winkler says that distance of 1 means equal string which is not the case here.
