Are there any best practices to follow when rounding numbers in PHP to ensure accuracy?

When rounding numbers in PHP, it is important to use the correct rounding function to ensure accuracy. One common issue is floating-point precision errors that can occur when performing mathematical operations on decimal numbers. To avoid these errors, it is recommended to use the `round()` function with the appropriate precision parameter.

$number = 10.555;
$rounded_number = round($number, 2);
echo $rounded_number; // Output: 10.56
