Are there any specific PHP functions or methods that should be avoided when converting decimal points?

When converting decimal points in PHP, it is important to avoid using functions like round(), ceil(), or floor() as they can introduce rounding errors. Instead, it is recommended to use the number_format() function with the appropriate precision parameter to accurately format decimal numbers.

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