What are some best practices for handling precision and rounding in PHP interval nesting algorithms?

When working with interval nesting algorithms in PHP, it is important to handle precision and rounding correctly to avoid unexpected results. One common approach is to round the interval boundaries to a specific number of decimal places before performing any calculations. This can help ensure consistency and accuracy in the nesting algorithm. 

function roundInterval($interval, $precision) {
    $start = round($interval['start'], $precision);
    $end = round($interval['end'], $precision);

    return ['start' => $start, 'end' => $end];
}

$interval = ['start' => 1.23456789, 'end' => 5.67890123];
$precision = 2;

$roundedInterval = roundInterval($interval, $precision);

var_dump($roundedInterval);
