How to increase precision with division in MySQL?
To increase precision with division, use MySQL CAST(). Let us first create a table −
mysql> create table DemoTable1823 ( Value int ); Query OK, 0 rows affected (0.00 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable1823 values(1); Query OK, 1 row affected (0.00 sec) mysql> insert into DemoTable1823 values(2); Query OK, 1 row affected (0.00 sec) mysql> insert into DemoTable1823 values(3); Query OK, 1 row affected (0.00 sec)
Display all records from the table using select statement −
mysql> select * from DemoTable1823;
This will produce the following output −
+-------+ | Value | +-------+ | 1 | | 2 | | 3 | +-------+ 3 rows in set (0.00 sec)
Here is the query to increase precision with division in MySQL −
mysql> select cast(Value AS DECIMAL(30, 20)) / 3 as Result from DemoTable1823;
This will produce the following output −
+----------------------------+ | Result | +----------------------------+ | 0.333333333333333333333333 | | 0.666666666666666666666667 | | 1.000000000000000000000000 | +----------------------------+ 3 rows in set (0.00 sec)
