Add note about aggregations on floats (#10285) 
* Add note about aggreations on floats

Floating point math is known to be unstable. Due to the way aggregators work
across segments it's possible for the same query operating on the same data to
produce slightly different results.

The same problem exists with any aggregators that are not commutative since
the merge order across segments is not guaranteed.

* Also talk about doubles

* Apply suggestions from code review
