Converting exponential value in java to a number format

Question

I am trying to read the values from excel sheet using java. When i type more than 10 letters in a cell in excel it is displaying in exponential form like \"9.78313E+2\". but

Answer 1

Have to convert the cell into number format before reading the cell value. Below is the code snippet that is used to get the actual value that is in exponential format:

nextCell.setCellType(XSSFCell.CELL_TYPE_NUMERIC);
Double doubleValue = nextCell.getNumericCellValue();
BigDecimal bd = new BigDecimal(doubleValue.toString());
long lonVal = bd.longValue();
String phoneNumber = Long.toString(lonVal).trim();
System.out.print("PhoneNumber " + phoneNumber);
