The Stdclass class is an internal retention class for PHP, with no member variables at the beginning and no member methods, all magic methods are set to null and can be used to pass variable arguments, but there is no method that can be invoked.

The following article focuses on the actual retention of the Oracle decimal point. If you have requirements for extracting the Business list, we need to use the percentage. Normally, we need to keep two decimal places for it. In fact, we can only use round (_ data, 2), but the format is not neat. If you do not have strict format requirements, you can use round.

Another Oracle decimal point retention problem is that when column is used, the setting takes effect at the session level or system level. Pay attention to this. Maybe the numeric column of a table does not
