C++ 取整取余

向下取整 floor

向上取整 ceil

 CString  streangle=_T("4.6259");
double  dangle= wcstod(streangle, NULL);
 int  idu=(int)floor(dangle);
   int ifen= (int)floor((dangle-floor(dangle))*60);
   double  fen=(dangle-floor(dangle))*60;
   double imiao=(fen-floor(fen))*60;

  TRACE(_T("%d ° %d \"  %.3f '"),idu,ifen,imiao);

%.3f 确定3位小数
