[jira] [Commented] (ARROW-12084) [C++][Compute] Add remainder and quotient compute::Function

    [ https://issues.apache.org/jira/browse/ARROW-12084?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17308737#comment-17308737 ] 

Neal Richardson commented on ARROW-12084:
-----------------------------------------

We have a bit of hackery in R to effect these with the existing compute kernel: https://github.com/apache/arrow/blob/master/r/R/expression.R#L71-L90

Would be great to delete that.

> In addition to {{divide}} which returns only the quotient, it'd be useful to have a function which returns both quotient and remainder (these are efficient to compute simultaneously), probably as a {{struct<quotient: T, remainder: T>}}.
