Incorrect value when retrieve number from downloaded SSRS Excel

```
What steps will reproduce the problem?
I download xls file from SSRS.
I use this simple code below to read the file :

$data = new Spreadsheet_Excel_Reader($file);
$data->val($row,$col);

the column value is 1,040,809,656.00
output from code above is
[$-1,040,809,6561,040,809,6561,040,809,6561,040,809,6561,040,809,6561,040,809,65
61,040,809,656]1,040,809,6561,040,809,6561,040,809,6561,040,809,656.1,040,809,65
61,040,809,656

What is the expected output? What do you see instead?
the expected value is 1,040,809,656.00 (same value of excels)

Please provide any additional information below.
is there any possibility of encode setup?
because if i open and resave in Excel97/2000/XP type, the value will be
retrieved as excel value (ex : 1,040,809,656.00)

Start by reproducing the issue with the SSRS-downloaded XLS file and the Spreadsheet_Excel_Reader->val($row, $col) entry point. Compare its result with the Excel value shown in the report, and consider the issue resolved when the reader returns 1,040,809,656.00 without requiring the file to be resaved.
