Java Jxl read/writing to workbook

Question

I have an asset spreadsheet(excel) with decimal mumbers (ie. 30.50), but can only run the code below if the cells are formatted to "no decimal places" (30) otherwise it gives me the error below. The error displays the float as 30,50 with comer instead the original 30.50 !!!

Need to convert string rCell to float.

rCell = readCell.getContents();
float testnumber = Float.parseFloat(rCell);

////////****** Read asset EXCEL File ****///////////

AssetManager assetManager = getAssets();
InputStream inputStream = null;
  try {
      inputStream = assetManager.open("MyFile.xls");
      } catch (IOException e) {
      e.printStackTrace();
      }
try {
    readAsset = Workbook.getWorkbook(inputStream);
    } catch (IOException e) {
    e.printStackTrace();
    } catch (BiffException e) {
    e.printStackTrace();
    }
Sheet s = readAsset.getSheet(0);

////////////////////////////////****** WRITE Excel TO SD ***/////////////

    Fnamexls="testfile"  + ".xls";
    File sdCard = Environment.getExternalStorageDirectory();
    directory = new File (sdCard.getAbsolutePath() + "/MyFolder");
    directory.mkdirs();
    sdFile = new File(directory, Fnamexls);

        wbSettings = new WorkbookSettings();
        wbSettings.setLocale(new Locale("en", "EN"));
        try {
            wrWorkbook = Workbook.createWorkbook(sdFile, wbSettings);
            writeSheet = wrWorkbook.createSheet("First Sheet", 0);
            int row = s.getRows();
            int col = s.getColumns();
            //xx = "";
            for (int c = 0; c < col; c++) {
                for (int r = 0; r < row; r++) {
                    Cell z = s.getCell(c, r);
                    xx = z.getContents();
                    Label label4 = new Label(c, r, String.valueOf(xx));
                    try {
                        writeSheet.addCell(label4);
                    } catch (RowsExceededException e) {

Found it. I set the Locale in Main() Locale.setDefault(new Locale("en", "US"));
