How to format number to 2 decimal places in MySQL?

MySQLMySQLi Database

You can use TRUNCATE() function from MySQL to format number to 2 decimal places. The syntax is as follows −

SELECT TRUNCALTE(yourColumnName,2) as anyVariableName from yourTableName;

To understand the above syntax, let us first create a table. The query to create a table is as follows −

mysql> create table FormatNumberTwoDecimalPlace
   -> (
   -> Number float
   -> );
Query OK, 0 rows affected (0.59 sec)

Insert some records in the table using insert command. 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 display all records from the table using select command. The query is as follows −

mysql> select *from FormatNumberTwoDecimalPlace;

Output

+---------+
| Number  |
+---------+
| 123.456 |
|  1.6789 |
|    12.2 |
| 12356.2 |
|   12356 |
|  0.5678 |
+---------+
6 rows in set (0.04 sec)

Here is the query to format number to two decimal places −

mysql> select truncate(Number,2) as TwoValueAfterDecimal from
FormatNumberTwoDecimalPlace;

Output

+----------------------+
| TwoValueAfterDecimal |
+----------------------+
|               123.45 |
|                 1.67 |
|                12.19 |
|             12356.23 |
|             12356.00 |
|                 0.56 |
+----------------------+
