Raúl Cumplido updated ARROW-14028:
----------------------------------
Fix Version/s: 9.0.0
(was: 8.0.0)
> [R] Cast of NaN to integer should return NA_integer_
> ----------------------------------------------------
>
> Key: ARROW-14028
> URL: https://issues.apache.org/jira/browse/ARROW-14028
> Project: Apache Arrow
> Issue Type: Improvement
> Components: R
> Reporter: Ian Cook
> Priority: Major
> Fix For: 9.0.0
>
>
> Casting double {{NaN}} to integer returns a sentinel value:
> {code:r}
> call_function("cast", Scalar$create(NaN), options = list(to_type = int32(),
> allow_float_truncate = TRUE))
> #> Scalar
> #> -2147483648
> call_function("cast", Scalar$create(NaN), options = list(to_type = int64(),
> allow_float_truncate = TRUE))
> #> Scalar
> #> -9223372036854775808{code}
> It would be nice if this would instead return {{NA_integer}}.
> N.B. for some reason this doesn't reproduce in dplyr unless you round-trip it
> back to double:
> {code:r}
> > Table$create(x = NaN) %>% transmute(as.double(as.integer(x))) %>% pull(1)
> #> [1] -2147483648{code}
