[gdal-dev] OFTReal values truncated to integer

[diegogb]

I have a problem on storing double values on shapefiles fields.
If I execute this code:

//...
OGRFieldDefn zField("Elev", OFTReal);
layer->CreateField(&zField);
//...
OGRFeature *pointFeature = OGRFeature::CreateFeature(layer->GetLayerDefn());
OGRPoint thePoint;
thePoint.setX(1);
thePoint.setY(1);
thePoint.setZ(1);
pointFeature->SetGeometry(&thePoint);
double myVal = 1.3;
pointFeature->SetField("Elev", myVal);
layer->CreateFeature(pointFeature);
OGRFeature::DestroyFeature(pointFeature);
// Close data source etc.

When I open with Quantum GIS the file created by my program, the field
"Elev" does not contains 1.3 but 1. Why?!?
If i edit the file on QGIS, i can write 1.3 instead of 1, so the field type
is real and not integer...
I'm a GDAL newbie, but the code is so simple that i can't figure where is
the problem!

Thanks.
