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

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 integerround-off 是指，不一定是 up 或者down, 就看哪个最近

Answer

向上取最近的5的倍数 比如31就取35
向下取最近的5的倍数 比如31就取30
取最近的5的倍数

(向上/向下/??)保留2位小数
(向上/向下/??)取整

round-off有可能是"直接取整" "直接保留2位小数" 但不太确定

Answer

round off 是四舍五入的意思

Answer

进至最近的整数，且该数须为5的倍数。（比如：31进至35）
退＊＊＊＊＊＊，＊＊＊＊＊＊＊＊＊。（比如：31退至30）
取最近的整数，且该数须为5的倍数。（比如：31取30，33取35）

进至/退至/取至小数点后保留两位。
＊＊/＊＊/＊＊最近的整数。
