疑似涨停价错误

今天运行策略，标的eg2610，用语句： data[f*i+1].myuplimit=data[f*i+1].RoundDown(mysettleprice[0][0]*(1+0.01*data[f*i+1].mypricelimit[0][0])/myjump,0)*data[f*i+1].myjump; data[f*i+1].mydnlimit=data[f*i+1].RoundUp(mysettleprice[0][0]*(1-0.01*data[f*i+1].mypricelimit[0][0])/myjump,0)*data[f*i+1].myjump; data[f*i+1].Commentary("2;myuplimit="+text(myuplimit,0)+";mydnlimit="+ text(mydnlimit,0));发现代码计算给出了的myuplimit=6315，而实际=6530.请告知是我的错还是系统错误？
