How can the PHP code for normalizing float values be improved to ensure database compatibility?

When working with float values in PHP, it is important to normalize them to ensure consistency and compatibility with databases. One common issue is the precision of float values, which can lead to unexpected results when storing or retrieving data from a database. To improve compatibility, you can round float values to a specific number of decimal places before storing them in the database.

// Normalize float value to 2 decimal places
$floatValue = 123.456789;
$normalizedValue = round($floatValue, 2);

// Insert normalized value into database
$query = "INSERT INTO table_name (float_column) VALUES ($normalizedValue)";
// Execute query
