How can the use of a specific rounding algorithm for determining values in a database table pose challenges for future updates or modifications?

Using a specific rounding algorithm for determining values in a database table can pose challenges for future updates or modifications because if the algorithm is changed or updated, it may lead to inconsistencies in the data stored in the database. To avoid this issue, it is recommended to store the raw data in the database and perform the rounding calculations dynamically when retrieving or displaying the data.

// Store raw data in the database table
$query = "INSERT INTO table_name (raw_value) VALUES ($rawData)";
$result = mysqli_query($connection, $query);

// Retrieve and round data dynamically when needed
$query = "SELECT raw_value FROM table_name";
$result = mysqli_query($connection, $query);

while($row = mysqli_fetch_assoc($result)) {
    $roundedValue = round($row['raw_value'], 2); // Round to 2 decimal places
    echo "Rounded Value: " . $roundedValue;
}
