----------------------------------------------------------
Yes, Glog/gtest has similar macro/function to check double, but not sure are we
going to copy it into {{stout}} or are we going to use fixed precision (e.g.
0.01) in Mesos.

> Check failed: result.cpus() == cpus() && result.mem() == mem() &&
> result.disk() == disk() && result.ports() == ports()

> Issue Type: Bug
> Components: master
> Affects Versions: 0.24.1

>
> result.cpus() == cpus() check is failing due to ( double == double )
> comparison problem.
> Root Cause :
> Framework requested 0.1 cpu reservation for the first task. So far so good.
> Next Reserve operation — lead to double operations resulting in following
> double values :
> results.cpus() : 23.9999999999999964472863211995 cpus() : 24
> And the check ( result.cpus() == cpus() ) failed.
> The double arithmetic operations caused results.cpus() value to be :
> 23.9999999999999964472863211995 and hence ( 23.9999999999999964472863211995
> == 24 ) failed.
