Consider the following table about some students:

4 | Arthur | David | 2016-04-01 | 16 | adavid4 |
5 | Benjamin | Town | 2014-01-01 | 17 | btown5 |
The above sample table can be created using the code here.
Basic usage
To return the largest integer smaller than or equal to -13.5:
SELECT FLOOR(-13.5);
+--------------+| FLOOR(-13.5) |+--------------+| -14 |+--------------+1 row in set (0.01 sec)
To return the largest integer smaller than or equal to the average age of students:
SELECT FLOOR(AVG(age)), AVG(age)FROM students;
+-----------------+----------+| FLOOR(AVG(age)) | AVG(age) |+-----------------+----------+| 17 | 17.4000 |+-----------------+----------+1 row in set (0.01 sec)
