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. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
