Neil Conway commented on MESOS-3997:
------------------------------------
Should probably do the same thing for weights.
> Switch to fixed-point for resources

> Key: MESOS-3997
> URL: https://issues.apache.org/jira/browse/MESOS-3997
> Project: Mesos
> Issue Type: Improvement
> Components: allocation, master
> Reporter: Neil Conway
> Labels: mesosphere, resources
>
> Using floating point for resources is problematic, because roundoff and
> precision errors when doing resource math can produce unexpected results.
> Instead, we should probably adopt a fixed-point representation: e.g., CPU
> resources will be measured as an integer number of fractional CPUs (e.g., 25
> deci-CPUs == 2.5 CPUs).
