Are there any best practices or guidelines for handling numerical calculations and formatting in PHP?

When handling numerical calculations and formatting in PHP, it is important to ensure proper precision and formatting to avoid rounding errors or unexpected results. One best practice is to use the number_format() function to format numbers with desired decimal places and thousands separators. 

// Example of formatting a number with 2 decimal places and a comma as a thousands separator
$number = 12345.6789;
$formatted_number = number_format($number, 2, '.', ',');
echo $formatted_number; // Output: 12,345.68
