+
+The SQL math function **`ROUND()`** returns the number rounded to the specified number of decimal places. If no decimal places are provided, the number is rounded without decimals.
+
+> **Note:** In some RDBMS like SQL Server, there may be an optional third parameter to truncate instead of round.
+
+## Syntax
+
+```sql
+ROUND(number, decimals)
+```
+
+**Parameters:**
+
+- `number`: The number to be rounded.
+- `decimals` (optional): The number of decimal places to round to.
+
+**Return value:**
+
+Returns the number rounded to the specified number of decimal places.
+
+## Example 1
+
+In this example, the `ROUND()` function is used with a single argument.
+
+```sql
+SELECT ROUND(25.50); -- Result: 26
+```
+
+## Example 2
+
+In this example, the following data is given in the `sales` table:
+
+| id  | total   |
+| --- | ------- |
+| 1   | 123.456 |
+| 2   | 987.654 |
+
+The `ROUND()` function is used with the second optional argument `decimals`, setting the number of decimal places to 1:
+
+```sql
+SELECT id, ROUND(total, 1) AS total_rounded FROM sales;
+```
+
+In this SQL statement, the total values are rounded to get the total_rounded. The [AS](https://www.codecademy.com/resources/docs/sql/commands/as) keyword is used to name the resulting column total_rounded in the output.
+
+The output will be:
+
+| id  | total_rounded |
+| --- | ------------- |
+| 1   | 123.5         |
+| 2   | 987.7         |
