If you export with r.out.gdal you can choose among

      type   File type
              options: Byte,Int16,UInt16,Int32,UInt32,Float32,Float64,CInt16,
                       CInt32,CFloat32,CFloat64

This is the range which GRASS support for export to GDAL
supported formats (of course it depends if the format is compatible
with the selected type, see GDAL manual pages for details).
