Signatures & examples

round ( numeric ) → numeric
Rounds to nearest integer. For numeric, ties are broken by rounding away from zero. For double precision, the tie-breaking behavior is platform dependent, but “round to nearest even” is the most common rule.
round(42.4) → 42
round ( double precision ) → double precision
Rounds to nearest integer. For numeric, ties are broken by rounding away from zero. For double precision, the tie-breaking behavior is platform dependent, but “round to nearest even” is the most common rule.
round(42.4) → 42
round ( v numeric, s integer ) → numeric
Rounds v to s decimal places. Ties are broken by rounding away from zero.
