I'm using v16.2.20162.2045 and getting an OverflowException when using the XamSpreadsheet and a locale. In this particular example, I am setting cells to a Double value with decimals like 3.1415926535.  The Workbook.Culture behind the scenes is set to Persian (Iran).

When the spreadsheet is displayed, the numbers are shown in their native characters.  When a cell is double clicked, it goes into edit mode and shows what looks like a fraction in English numerals (1/2343135423).  When the cell loses focus, the exception occurs.

Any ideas?

System.OverflowException occurred
HResult=-2146233066
Message=Value was either too large or too small for an Int32.
