MySQL Command: ROUND()

MySQL Command: ROUND()

In the world of databases, MySQL is one of the most popular choices for managing and manipulating data. It offers a wide range of functions and commands that allow users to perform various operations on their data. One such command is the ROUND() function, which is used to round a number to a specified number of decimal places.

Syntax

The syntax for the ROUND() function is as follows:

ROUND(number, decimals)

Here, number is the value that you want to round, and decimals is the number of decimal places to which you want to round the number. If the decimals parameter is omitted, the ROUND() function will round the number to 0 decimal places by default.

Examples

Let's take a look at some examples to understand how the ROUND() function works:

Example 1:

SELECT ROUND(3.14159, 2);

This query will return the value 3.14, as the ROUND() function rounds the number 3.14159 to 2 decimal places.

Example 2:

SELECT ROUND(6.789);

In this example, the ROUND() function will round the number 6.789 to 0 decimal places, resulting in the value 7.

Example 3:

SELECT ROUND(9.87654, -2);

Here, the ROUND() function will round the number 9.87654 to -2 decimal places. Rounding to a negative number of decimal places means rounding to the nearest 10, 100, 1000, and so on. In this case, the result will be 10.

Conclusion

The ROUND() function in MySQL is a powerful tool for rounding numbers to a specified number of decimal places. It allows users to manipulate and format their data according to their needs. Whether you need to round a number to 2 decimal places or round it to the nearest 10, the ROUND() function has got you covered.
