object type application, in order to share the same object, you can use ref to refer to the object type, which is actually a pointer to an object instance.The following example shows how to use REF. First establish the object type home and object Table homes, and then insert the data.CREATE OR REPLACE TYPE home_type as OBJECT (Street VARCHAR2 (50),City Varchar2 (20),State VARCHAR2 (20),ZipCode VARCHAR2 (6),Owner VARCHAR2 (10));/CREATE TABLE
relatively simple. When the number of rounding digits is smaller than 5, the number is directly rounded off. When the number of rounding digits is greater than or equal to 5, move forward when this digit is removed. Keep a note to keep you informed:"Four, five".
Bankers have complicated rounding rules. The following is an excerpt from Baidu Encyclopedia:
The so-called bankers rounding method is essentially a four-house six-in-five pair (also known as four-house six-in-five-stay pair) met
1.Round(Four homes, six homes, five homes)
Function Description: rounds a real number. (Based on the banker's algorithm)
Example:VaRI, J: integer;BeginI: = round (1.5); // I equals 2J: = round (2.5); // J equals 2End;
InDelphiThe answer obtained by using the round function in is sometimes different from what we expected: four

In [3]: df = pd.DataFrame([['GD', 'GX', 'FJ'], ['SD', 'SX', 'BJ'], ['HN', 'HB' ...: , 'AH'], ['HEN', 'HEN', 'HLJ'], ['SH', 'TJ', 'CQ']], columns=['p1', 'p2 ...: ', 'p3'])In [4]: dfOut[4]: p1 p2 p30 GD GX FJ1 SD SX BJ2 HN HB AH3 HEN HEN HLJ4 SH TJ CQ
If you only want two rows whose p1 is GD and HN, you can do this:
