round

round(number) → integer · Math

Round to the nearest integer (half-up rounding).

• number (required): the number to round

round(3.5)      // 4
round(3.4)      // 3
round(-3.5)     // -3

// Round to 2 decimal places (common pattern for currency):
round(6.2895 * 100) / 100               // 6.29

Anti-pattern: round(price) for currency — loses cents entirely. Use roundToCents(price) or roundToDecimalPlaces(price, 2) instead.
