What are the potential issues with using number_format() in PHP?

One potential issue with using number_format() in PHP is that it may not handle large numbers correctly, as it can round the number in unexpected ways.

$number = 1234567890.12345;
$formatted_number = number_format($number, 0, '.', ',');
echo $formatted_number;
