貼代碼
for(j=6;j<=3;j-=1)
{
p_my_buy_info=p_my_buy_info_bak;
for(i=0;i<All_Number;i++)
{
if(i!=0)
p_my_buy_info++;
if(p_my_buy_info->my_StockRating_Total==0.0000) continue;
if(fabs((double)j-p_my_buy_info->my_StockRating_Total)<1E-3)
{
n_stock_Out2++;
if(n_stock_Out2<=450)
{
strcat(s_tmp2,p_my_buy_info->my_Code);
strcat(s_tmp2,"\n");
}
}
}
}
這里一個問題是p_my_buy_info->my_StockRating_Total原來賦值就是通過
p_my_buy_info->my_StockRating_Total=(double)5 ; //這么賦值的
然后不用回圈體，一個個堆起來卻可以。、好頭疼，百思不得其解
/* 還是錯誤

這種卻可以出來正確結果，為啥？誤差這么大嗎？
求幫助。
