Description
Rounds A to the nearest integer, rounding half-values away from zero (e.g. 1.5 → 2, -1.5 → -2). Returns an int32.
Caveats & Gotchas
- • The result is int32, so values outside the int32 range (-2,147,483,648 to 2,147,483,647) will overflow silently — use Round64 for large values.
- • Uses round-half-away-from-zero, not round-half-to-even (banker's rounding) — this can introduce small systematic bias when accumulating many rounded values.
