Felix Abecassis commented on MESOS-1187:
----------------------------------------
You are right that it can get extremely complex. We are not doing scientific
computing here so I don't think we need to go to such depths as computing ULPs
and handling subnormals :).
I think a simple relative epsilon comparison will do the trick just fine.
For instance function AlmostEqualRelative in:

> precision errors with allocation calculations

> As allocations are stored/transmitted as doubles many a times precision
> errors creep in.
> we have seen erroneous share calculations happen only because of floating
> point arithmetic.
