Xcart the number of decimal places by default is 2 bits, sometimes need to change the number of bits as needed; At first, the number of bits in the data type in the database can be changed, and the result is that Xcart is limited in the program, only 2 bits. Then only by changing the way the program to change, because of time jincu, only make simple changes (it is possible to add a variable in general setti
