duckdb ``` memory D SELECT round(2.5::float8); ┌──────────────────────────────┐ │ round(CAST(2.5 AS "DOUBLE")) │ │ double │ ├──────────────────────────────┤ │ 3.0 │ └──────────────────────────────┘ ``` should match PG half-tie behavior, DuckDB uses half-away-from-zero uniformly across all numeric types. PG is split: round(numeric) = half-away-from-zero, round(double) = half-to-even (delegated to libc rint(), platform-dependent). DuckDB explicitly exposes the PG-style banker's rounding as the separate round_even() / roundbankers() functions, suggesting round() was deliberately chosen as non-banker's. -- This is an automated message from the Apache Git Service.
