Subject [jira] [Commented] (LUCENE-7938) Bounds of bounding box are not equal to bounding box
Date Mon, 21 Aug 2017 17:35:00 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-7938?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16135482#comment-16135482

Karl Wright commented on LUCENE-7938:
-------------------------------------

[~ivera], this is by design.  Bounding boxes are supposed to *contain* the objects within;
there are indeed some rare cases where it is difficult to compute the bounding box and we
return a larger box as a shortcut.

Furthermore, you should not modify the "equals" method to allow a match that is not a precise
object match; that's a violation of the contract of "equals".

I'm going to close this as "not a bug".

> Hi,
> It seems if I get the bounds of a BBox and I create a new bounding box, sometimes both
bounding box are not equal. It is a problem with precision.
