sqlite SUM result decimal gone

Test Code :

> String x = "30000000000.222";
> String y = "20000000000.444"; 
> double x1 = Double.parseDouble(x);  
> double y1 = Double.parseDouble(y);
> 
> ContentValues vValue51 = new ContentValues();
> vValue51.put(DatabaseStructure.fTmpAttr_X3         , x1 );
> vDatabase.insertData(DatabaseStructure.cTblTemporary3, vValue51);
>            ContentValues vValue61 = new ContentValues(); vValue61.put(DatabaseStructure.fTmpAttr_X3        , y1 );
> vDatabase.insertData(DatabaseStructure.cTblTemporary3, vValue61);
> vDatabase.closeDatabase();
> 
> 
> 
> List<Map<String, String>> vListData2 = new
> ArrayList<Map<String,String>>(); String vQuerY32;
>           
> 
>            vQuerY32 = "Select SUM(" + DatabaseStructure.fTmpAttr_X3 + " ) 'jik' " + 
>          "From " + DatabaseStructure.cTblTemporary3; 
> 
>           vDatabase = new DatabaseHandler(getApplicationContext());
>           vListData2 = vDatabase.getListData(vQuerY32);
>           vDatabase.closeDatabase();

I tried many data type for column

> vQuery = "create table " + cTblTemporary3 +
>                "("+
>                fTmpAttr_ID3 + " integer primary key, " +
>                fTmpAttr_V3  + " DECIMAL(10,5), " +
>                fTmpAttr_W3  + " FLOAT , " +
>                fTmpAttr_X3  + " REAL, " +
>                fTmpAttr_Y3  + " DOUBLE PRECISION, " +
>                fTmpAttr_Z3  + " double " +
>                ")";       vSQL.execSQL(vQuery);

i Log the result

Log.d("TEST", vListData2.get(0).get("jik"));

, the result is not 50000000000.666 but 5e+10, How i can get 50000000000.666 for the result? Please help this newbie :(
