四舍五入到最接近的 5 美分
Rounding to the closest 5 cents
我有一个要求,要求金额值应四舍五入到最接近的 5 美分到小数点后两位。
Example:
255.263745 to 255.25 -- 26 taken to 25
57.2115 to 57.20 -- 21 taken to 20
100.75586 to 100.75
我尝试了以下方法,但无法获得所需的输出。
select (RIGHT('00000000'+LEFT( CAST(CAST( ISNULL(198.85,0)*ISNULL(128.370,0) AS DECIMAL( 15,0)) AS VARCHAR( 15 )), 8 ), 8 ))
select CEILING(((ISNULL(198.85,0) * (ISNULL(128.370,0)/100)))/.05) *.05
工作样本:
SELECT REPLACE(FORMAT(CAST(ROUND(((ISNULL(198.85,0) * (ISNULL(128.370,0)/100)/05)),2)*05 AS DECIMAL(10,2)),'000000.00'),'.','') AS [Actual Amount]
输出:00025525
你可以这样做:
round(mycol / 5, 2) * 5
或者如果你真的想严格控制输出数据类型:
cast(round(mycol / 5, 2) * 5 as decimal(10,2))
select mycol, cast(round(mycol / 5, 2) * 5 as decimal(10,2)) res
from ( values (255.263745), (57.2115), (100.75586) ) t(mycol)
mycol | res
:--------- | :-----
255.263745 | 255.25
57.211500 | 57.20
100.755860 | 100.75
