Which SQLiteDataReader data type access method should I use for Single columns?

I am reading some values out of a SQLite database like so:

List<String> choctypusValsForUPCCode = new List<string>();
. . .
using (SQLiteDataReader rdr = cmd.ExecuteReader())
{
    choctypusValsForUPCCode.Add(rdr.GetInt32(0).ToString()); // Line_id (int32)
    choctypusValsForUPCCode.Add(rdr.GetString(1));  // Description (String)
    choctypusValsForUPCCode.Add(rdr.GetString(2));  // Department (String)
    choctypusValsForUPCCode.Add(rdr.GetString(3));  // Vendor_id (String)
    choctypusValsForUPCCode.Add(rdr.GetInt32(4).ToString());   // Upc_pack_size (int32)
    choctypusValsForUPCCode.Add(rdr.GetInt32(5).ToString());  // Pack_size (int32)
    choctypusValsForUPCCode.Add(rdr.GetFloat(6).ToString());  // Unit_cost (single) // GetDouble? GetDecimal?
    choctypusValsForUPCCode.Add(rdr.GetFloat(7).ToString());  // Unit_list (single) " "
    choctypusValsForUPCCode.Add(rdr.GetFloat(8).ToString());  // Unit_qty (single) " "
}

When the data type of the underlying column is Single, which "Get" method of SQLiteDataReader should I use (there is no "GetSingle")? Is GetFloat, GetDouble, or GetDecimal the preferred method?
