Michael McCandless commented on LUCENE-1777:
--------------------------------------------
bq. Actually there is already a floor on boxes level which cannot be > 15 in
the bestFit function.
Ahh OK. And from the comment in the code:
{quote}
if (bestFit > 15) {
// 15 is the granularity of about 1 mile
// finer granularity isn't accurate with standard java math
return 15;
}
{code}
It looks like 1 mile is the "natural" floor given Java's math... so I think we
should 1) switch miles to double, but 2) enforce a floor of 1.0, carrying over
this comment from bestFit to where that floor is enforced. I'll make those
changes under LUCENE-1504.
