Description

The following code:

<?php
echo number_format(3.1415, -1, ".", ",");

Resulted in this output since PHP 8.3.0:

0

But I expected this output instead:

3

No such change has been documented in https://www.php.net/manual/en/function.number-format.php

I understand -1 is not an expected value for $decimals, but if this change is intended I would have expected a E_WARNING or E_DEPRECATED before.

PHP Version
