Dawid Weiss commented on LUCENE-7185:
-------------------------------------
{code}
+ // may trigger divide by zero
+ return 0.0;
{code}
Given that ((Double) +0.0).equals/compareTo(-0.0) equals false, even though
unboxed comparison obviously equals true, I'd add -0.0 to the list of surprises
as well.

> The current method is not very good for testing.
> * It will only rarely or never return edge cases like -180/180/-90/90
> * It will only rarely return 0
> * There are many possible doubles within the ranges (-180..180/-90..90) it
> will never return
