Hi Mark,

You can use an OGR connection for formatting of number fields when labelling in MapServer version 5.x. I think you need GDAL 1.6 or later.

For example with a shapefile called test.shp with a field, testfld1, you can do the following to show only two decimal places.

LAYER
   ..
   CONNECTIONTYPE OGR
   CONNECTION "test.shp"
   DATA "select CAST(testfld1 AS numeric (4,2)) from test"
   ..
   CLASS
       ...
       TEXT ([testfld1)]
       LABEL
        ..
       END
   END
END

Regards,

Kathleen

Hello,

I have a label that displays a number in scientific notation;  for example 2.08+e002.  I would like the label to display as an integer such as 2.08.  In the past I asked a similar question about HTML templates and someone mentioned that I should use "[item name="area" precision=2]"  Unfortunately, the statement seems invalid as a label in the .map file.

Does anyone know how I can display a number as an integer?  Or will I have to convert all my values to Text?  I am using mapserver 5.4

Thanks

Mark
