floating equality

We've got binarySearch that search for doubles and floats without an
epsilon.  Does this bother sufficiently to change it?

We've got things like FloatArrayList, which implement a binary search,
which does equality.

I can suppress them for the float/double cases.

And don't ask me about boolean today.

Yes, is this exact-equality search even used? kill it if not.
I'd not even add your variant unless there's a need.
