One more thing...
It could optionally be indexed and stored as a String
then contents of the Hits object could be placed into
a Collection with a comparator that sorts double
values in reverse order.

Hi,
I'm trying to turn a double with decimal point
precision fifteen digits to the left into a sortable
String for Lucene (.346210426731253).
NumberTools is for longs so doesn't apply.
In Solr, NumberUtils.double2sortableStr prints
out a literal question mark character '?' .
I tried making it a float first but the formatting
also did not work w/NumberUtils.float2sortableStr.
Interestingly, I was able to write a BigDecimal
helper class, use setScale(15), longValue() then
pass it to NumberTools and get a padded result.
.346210426731253 becomes 000000
1.346210426731253 becomes 000001
2.346210426731253 becomes 000002
