請問這兩段為何出現不同結果

程式碼A

SumFund = Summation(GetField("投信買賣超"), 2);

sumVol = Summation(Volume, 2);

SumVolDayTrade = Summation(GetField("現股當沖張數"), 2);

SumFund / (SumVol - SumVolDayTrade) *100

程式碼B

for i=0 to (2)

   begin 

   SumVolDayTrade = SumVolDayTrade + getfield("現股當沖張數", "D")[i];

   SumFund = SumFund + getfield("投信買賣超", "D")[i];

   SumVol = SumVol + getfield("成交量", "D")[i];   

end;

SumFund / (SumVol - SumVolDayTrade) *100
