When I read a sheet into a DataTable using the OleDbDataReader, floating point numbers loose their precision.

I tried forcing OleDb to read the excel data as string, but although the data is now contained in a DataRow with each Column defined as System.String it looses precision (18.125 -> 18.124962832).

Any idea how to avoid this behaviour?
