Subject: [PATCH] Convert cell value to numbeic (float) in
 processDomElementDataFormat

If we want to use data-format attribute in html, we have to cast cell value to float (number). because format not applied to string values.
We should know excel put Leading apostrophes " ' " to numeric string values. Leading apostrophes force excel to treat the cell's contents as a text value.
