   I'm planning to implement decimalv3. The storage layer and computing layer will use a unified data type. Select the data type according to the precision, which can be int32, Int64 or int128. It will improve the precision of decimal and support up to 38 significant digits. It also can avoid the conversion between computing layer and storage layer, and make reading and evaluation faster.
