# ROUND

## Overview

The `ROUND()` function rounds numbers using round half to even method (bankers rounding).

## Syntax

The following illustrates the syntax of the `ROUND()` function:

```sql theme={null}
ROUND(number);
```

Where:

* `number`: The number to round, it can be positive, negative, or zero, and it can be an [Integer](/sql-reference/sql-data-types/numeric-type/numeric) or a [Double Precision](/sql-reference/sql-data-types/numeric-type/numeric).

## **Examples**

Let's explore some examples to see how the `ROUND()` function works.

### Case #1: **Basic Usage**

In this example, we round decimal numbers to integers:

```sql theme={null}
SELECT
    round(28.11) AS "round(28.11)",
    round(12.51) AS "round(12.51)",
    round(-9.11) AS "round(-9.11)",
    round(102.5) AS "round(102.5)",
    round(101.5) AS "round(101.5)",
    round(-40.51) AS "round(-40.51)";
```

The query will return the nearest integer for all provided values.

```sql theme={null}
 round(28.11) | round(12.51) | round(-9.11) | round(102.5) | round(101.5) | round(-40.51) 
--------------+--------------+--------------+--------------+---------------+---------------
           28 |           13 |           -9 |          102 |          102 |           -41
```

### Case #2: Using `ROUND` with Table

Suppose you have a table named **Product** that stores product prices with multiple decimal places. You want to round the prices.

```sql theme={null}
CREATE TABLE Product (
    ProductID INT,
    ProductName TEXT,
    Price DOUBLE PRECISION
);

INSERT INTO Product (ProductID, ProductName, Price)
VALUES
    (1, 'Widget A', 12.345),
    (2, 'Widget B', 34.678),
    (3, 'Widget C', 9.99),
    (4, 'Widget D', 45.00),
    (5, 'Widget E', 7.12345),
    (6, 'Widget F', 19.876), 
    (7, 'Widget G', 3.5),
    (8, 'Widget H', 29.999);
```

We use the `ROUND()` function to round the Price column when retrieving the data.

```sql theme={null}
SELECT ProductName, ROUND(Price) AS RoundedPrice FROM Product;
```

The result will display the product names along with their prices rounded.

```sql theme={null}
 productname | roundedprice 
-------------+--------------
 Widget A    |           12
 Widget B    |           35
 Widget C    |           10
 Widget D    |           45
 Widget E    |            7
 Widget F    |           20
 Widget G    |            4
 Widget H    |           30
```
