</span>
-----------------------------------------------------
Round Application Examples:

SELECT ROUND(8989.3652,2),--2 bits left after the decimal place, roundedROUND(8989.3652,-2),--Round 2 bits before the decimal place, rounded---Rounding of all decimal digits roundedROUND(8956.34,0),ROUND(8956.65,0),ROUND(8956.25,0), ---truncate data after rounding position of dataROUND(16081.83,0,-2),ROUND(16081.83,0,1),ROUND(16081.83,0,5),ROUND(16081.835,2,8),ROUND(16081.836,-2,6),ROUND(16081.83,-2,7)Go---Example: SQL Cancellation rounding method sharing---lost two bits after decimal place, do not take rounding operationsSelect round(8989.999,2,9)
