How to compare decimals in MySQL?

In MySQL, you can compare the size of decimal values using comparison operators such as >, <, >=, <=, and =. These operators are used to compare the size of two decimal values.

For example, if there is a decimal column named “value,” you can use the following query to compare its size:

Retrieve all records from the table where the value is greater than 10.5.

This will return all rows with a “value” greater than 10.5.

Additionally, comparing can be done using functions, as shown in the following example:

Choose all rows from the table where the value is rounded to two decimal places and is greater than 10.5 rounded to two decimal places.

The ROUND function is used here to compare decimal values by rounding them to two decimal places.

Please be mindful of the precision and decimal places when performing decimal comparisons to avoid errors caused by floating point precision issues.
