You can use MySQL's TRUNCATE() function to format a number to 2 decimal places. The syntax is as follows:
SELECT TRUNCATE(yourColumnName,2) as anyVariableName from yourTableName;
In order to understand the above syntax, let us first create a table. The query to create the table is as follows -
mysql> create table FormatNumberTwoDecimalPlace -> ( -> Number float -> ); Query OK, 0 rows affected (0.59 sec)
Use the insert command to insert some records in the table. The query is as follows −
mysql> insert into FormatNumberTwoDecimalPlace values(123.456); Query OK, 1 row affected (0.13 sec) mysql> insert into FormatNumberTwoDecimalPlace values(1.6789); Query OK, 1 row affected (0.19 sec) mysql> insert into FormatNumberTwoDecimalPlace values(12.2); Query OK, 1 row affected (0.14 sec) mysql> insert into FormatNumberTwoDecimalPlace values(12356.23145); Query OK, 1 row affected (0.40 sec) mysql> insert into FormatNumberTwoDecimalPlace values(12356); Query OK, 1 row affected (0.14 sec) mysql> insert into FormatNumberTwoDecimalPlace values(.5678); Query OK, 1 row affected (0.28 sec)
Let us now use the select command to display all the records in the table. The query looks like this −
mysql> select *from FormatNumberTwoDecimalPlace;
+---------+ | Number | +---------+ | 123.456 | | 1.6789 | | 12.2 | | 12356.2 | | 12356 | | 0.5678 | +---------+ 6 rows in set (0.04 sec)
This is the query to format a number to two decimal places −
mysql> select truncate(Number,2) as TwoValueAfterDecimal from FormatNumberTwoDecimalPlace;
+----------------------+ | TwoValueAfterDecimal | +----------------------+ | 123.45 | | 1.67 | | 12.19 | | 12356.23 | | 12356.00 | | 0.56 | +----------------------+ 6 rows in set (0.00 sec)
