[jira] [Resolved] (LUCENE-2544) Add 'divisor' to NumericField, allows for easy storage of full precision data, but indexing *starting* at lower precision.

     [ https://issues.apache.org/jira/browse/LUCENE-2544?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Steven Rowe resolved LUCENE-2544.
---------------------------------

       Resolution: Won't Fix
    Fix Version/s:     (was: 4.1)
    Lucene Fields:   (was: New)

Given the fact that this just provides sugar over existing functionality, and considering [~thetaphi‍]'s objections, and the two years with zero activity, resolving as Won't Fix.

> In some cases, we want to index a timestamp or some other high precision numeric at a much lower precision, but we still want to store the full precision data.
> Rather than have to do this with two Field objects in the Document, it'd be easier to provide NumericField with a divisor as well as prevision step. The divisor would apply before beginning the trie logic.
> most often, this is a divide by 1, but that will happen only during the constructor or setXXXValue() in NumericTokenStream.
> I have the patch for this, or i will after i isolate it.
