What are the best practices for rounding float values in PHP?

When working with float values in PHP, it is important to round them properly to avoid precision errors. One common way to round float values is to use the PHP built-in round() function. This function allows you to specify the number of decimal places to round to, as well as the rounding method (e.g., round up, round down, or round to the nearest integer).

$floatValue = 10.56789;
$roundedValue = round($floatValue, 2); // Round to 2 decimal places
echo $roundedValue; // Output: 10.57
