alamb opened a new issue, #161: URL: https://github.com/apache/arrow-rs/issues/161
*Note*: migrated from original JIRA: https://issues.apache.org/jira/browse/ARROW-11051 Minimal example {quote}use arrow::\{array::PrimitiveArray, datatypes::Int64Type}; fn main() \{ let mut s = vec![]; for _ in 0..32 \{ s.push(Some(1i64)); s.push(None); } let v: PrimitiveArray<Int64Type> = s.into(); dbg!(arrow::compute::sum(&v)); } {quote} dependency {quote}arrow = \{version = "2", features = ["simd"]} {quote} The following code in `compute::sum` is wrong. The bit mask is checked reversed. {quote} remainder.iter().enumerate().for_each(|(i, value)| \{ if remainder_bits & (1 << i) != 0 \{ remainder_sum = remainder_sum + *value; } }); {quote} -- This is an automated message from the Apache Git Service.
