Alan Woodward commented on LUCENE-7741:
---------------------------------------
One wrinkle here is that we have a lot of casting from double to float, in
order to fit stuff into Explanation.value. Might be worth opening up another
JIRA to change Explanations to use doubles instead? Scores will still be
floats, but we use Explanation for more than just scores now.

> As noted on LUCENE-7737, it would be nice to be able to get an explanation
> for DoubleValues values, particularly for things like complex spatial
> distance calculations.
