As of this PR, integer floor division (e.g., `1L %/% 0L`) does return a
surprising value (INT_MAX) (and I believe it did before too). Everything else
returns a float64 int. I wasn't sure how to fix that using the machinery that I
know about but perhaps there is a way?
``` r
# remotes::install_github("apache/arrow/r")
library(arrow, warn.conflicts = FALSE)
library(dplyr, warn.conflicts = FALSE)
RecordBatch$create(number = 1L) %>%
mutate(floordiv = number %/% 0L) %>%
collect()
#> # A tibble: 1 × 2
#> number floordiv
#> <int> <int>
#> 1 1 2147483647
```
