如何让excel函数算出的数字保留小数点后两位并且四舍五入

B1=round(MAX((A1)*{0.03,0.1,0.2,0.25,0.3,0.35,0.45}-{0,105,555,1005,2755,5505,13505},0),2)
C1C1=round(IF(A1> 80000,A1*0.45-13505,IF(A1 > 55000,A1*0.35-5505,IF(A1 > 35000,A1*0.3-2755,IF(A1 > 9000,A1*0.25-1005,IF(A1 > 4500,A1*0.2-555,IF(A1 >1500,A1*0.1-105,IF(A1 >0,A1*0.03,0 ) ) ) ) ) ) ),2)
四舍五入的函数round（数据或公式，要保留的小数位）
