英文翻译成中文:
Round-up to the closest multiple of 5 (比如 round-up: 31 > 35)
Round-down to the closest multiple of 5 (比如 round-down: 31 > 30)
Round-off to the closest multiple of 5 (比如 round-off: 31 > 30 / 33 >35)
(Round-up / down / off) to 2 decimal places
(Round-up / down / off) to the closest integerround-off 是指,不一定是 up 或者down, 就看哪个最近
