POI读取excel里的数字问题

excel里的格字的内容是“47643300”，使用POI读出来变成了“24.76433E7”
咋让他原汁原味的读出来啊 public static void main(String[] args) throws Exception {
HSSFWorkbook excel = new HSSFWorkbook(new POIFSFileSystem(
new FileInputStream("D:\\longgang.xls")));
HSSFSheet sheet = excel.getSheet("sheet1");
HSSFRow row = sheet.getRow(sheet.getLastRowNum());
for (int i = row.getFirstCellNum(); i <= row.getLastCellNum(); i++) {
HSSFCell cell = row.getCell(i);
CellReference cellRef = new CellReference(i, cell.getColumnIndex());
System.out.print(cellRef.formatAsString());
switch (cell.getCellType()) {
case Cell.CELL_TYPE_STRING:
System.out.println(cell.getRichStringCellValue().getString());
break;
case Cell.CELL_TYPE_NUMERIC:
if (DateUtil.isCellDateFormatted(cell)) {
System.out.println(cell.getDateCellValue());
} else {
System.out.println(cell.getNumericCellValue());
}
break;
case Cell.CELL_TYPE_BOOLEAN:
System.out.println(cell.getBooleanCellValue());
break;
case Cell.CELL_TYPE_FORMULA:
System.out.println(cell.getCellFormula());
break;
default:
System.out.println();
}
}
}
