Are there any best practices for rounding numbers to a specific precision in PHP?

When rounding numbers to a specific precision in PHP, a common practice is to use the `round()` function along with the desired precision as the second argument. This function will round the number to the specified precision. Another approach is to multiply the number by the desired precision, round it to the nearest integer, and then divide it back by the precision to get the rounded number.

// Using round() function
$number = 123.456789;
$roundedNumber = round($number, 2);
echo $roundedNumber;

// Using multiplication and division
$number = 123.456789;
$precision = 100; // 2 decimal places
$roundedNumber = round($number * $precision) / $precision;
echo $roundedNumber;
