Are there any recommended best practices for handling numerical precision in PHP?

When working with numerical values in PHP, it's important to be mindful of numerical precision issues that can arise due to the way floating-point numbers are represented in the language. To handle this, you can use the PHP function `round()` to round numbers to a specified precision level.

// Example of rounding a number to 2 decimal places
$number = 10.123456789;
$roundedNumber = round($number, 2);
echo $roundedNumber; // Output: 10.12
