You need to apply a style to the cell. The style can include a number format.
DataFormat format = workbook.createDataFormat();
short fmt = format.getFormat("#0.0");
CellStyle style = workbook.createCellStyle();
style.setDataFormat(fmt);
…
cell.setCellStyle(style);

And one more thing, this is my source code:
public static void main(String str[]) throws Exception {
Map<String, Object> input = new LinkedHashMap<>();
SXSSFWorkbook workbook = new SXSSFWorkbook();
OutputStream os = new FileOutputStream(
new File("/home/gaian/Desktop/Sal.xlsx"));
workbook.setCompressTempFiles(true);
SXSSFSheet sheet = workbook.createSheet("firstSheet");
SXSSFRow row = sheet.createRow(0);
SXSSFCell cell = row.createCell(0);
cell.setCellValue("salary");
cell.setCellType(CellType.STRING);
row = sheet.createRow(1);
cell = row.createCell(0);
cell.setCellValue(new Double("4.0"));
cell.setCellType(CellType.NUMERIC);
workbook.write(os);
os.close();
workbook.close();
System.out.println("done creating excel workbook...");
}
I am creating a workbook and writing a value (4.0) as double in a sheet. But
when I open the sheet, I see the integral value 4 instead of decimal 4.0.
Any settings I need to do in my code to get the value 4.0?
Thanks.
Thanks,

Thanks so much Tim and Fanning. Both of your suggestions are working out. I
would suggest better to have such example in the test case section of your
source folder.

You need to make your SAXReader namespace aware:
