Hi,
It can be done alternatively without changing logic or disturbing yur data table if you are using data export.
The data export extracts the data table value in MS EXcel sheet1. you can prepare sheet 2 with formula you want (for getting decimals use divided by 10 or 100 ) related with sheet 1 cells. now store it in excel template folder located inside dataexport installed path.
Now while fetching data using data export in the left bottom corner of dataxport window, select use excel template.
then you will get decimal value or e-mc square so on in excel sheet 2 in the sheet 1 your datatable value will be there.
