23

Nearest whole number — no decimal places. The tenths digit decides: 5⁠–⁠9 round up, 0⁠–⁠4 keep; the decimals are dropped.

Exactly halfway between 22 and 23 — equally close to both. The halfway rule rounds away from zero, as in school and Excel ROUND: 23. Round half to even (banker's rounding) gives 22.
