But sometimes this can be really > unintuitive. For example, the sum of two int32 time series results in a > double. > Since we have the metadata of every time series that takes part in the > calculation, we can implement type inference to make the results more > intuitive. -- This message was sent by Atlassian Jira (v8.3.4#803005)
