How It Works
Standard rounding rounds to the nearest value, 0.5 rounds up. Round Up always goes to the next higher value. Round Down always goes to the next lower value. Banker's rounding rounds 0.5 to the nearest even digit to reduce bias.
Round: round(n × 10^d) / 10^d | Ceil: ceil(n × 10^d) / 10^d | Floor: floor(n × 10^d) / 10^d
