What potential pitfalls should be considered when using double data types in MySQL with PHP?

When using double data types in MySQL with PHP, it is important to be cautious of precision issues that may arise due to the way floating-point numbers are stored. To avoid potential pitfalls, it is recommended to use the DECIMAL data type in MySQL for storing decimal numbers with precise calculations. 

// Example of using DECIMAL data type in MySQL with PHP
$amount = 10.50;
$mysqli = new mysqli("localhost", "username", "password", "database");

// Prepare and execute query using DECIMAL data type
$stmt = $mysqli->prepare("INSERT INTO table_name (amount) VALUES (?)");
$stmt->bind_param("d", $amount);
$stmt->execute();
