> Improve output size calculation in conv2d & max_pool2d
> ------------------------------------------------------

> Key: SYSTEMML-1516
> URL: https://issues.apache.org/jira/browse/SYSTEMML-1516
> Project: SystemML
> Issue Type: Sub-task
> Reporter: Mike Dusenberry
> Assignee: Mike Dusenberry
> Priority: Minor
>
> The calculation of the output sizes (`Hout`, `Wout`) for conv2d and
> max_pool2d layers rely on a flooring operation to only allow for valid
> operations. Currently, we simply rely on the `as.integer` call to
> implicitly perform this flooring operation during truncation of the double
> to an integer. While this gives the correct results, it is less
> readable than it should be, and relies on truncation behavior than explicit
> mathematical behavior. We should simply add an explicit `floor`
> operation to each calculation.
