[gdal-dev] How to change displayed decimal places of double type in the method: OGRFeature::SetField

[Chaitanya kumar CH]

Tai,

DBF formats allows specifying the precision of decimal values.
Check the field definition of the .dbf file using ogrinfo. If it shows a
precision of 2, you did all you can with OGR.

Excel, on the other hand, may have different rules. There is not much that
can be done with .dbf files to control the view in Excel.
