This also is not in these pages
https://www.php.net/manual/en/migration80.incompatible.phphttps://www.php.net/manual/en/migration80.deprecated.phphttps://www.php.net/manual/en/migration80.other-changes.php
I could not find info about this and just let my php run until one day there are unknown errors and
I find out that it is incompatible.
<?php
$num = '1.00';
var_dump(abs($num));// working fine until PHP 8.0+
?>
Maybe please update any one of these page.

Description:
------------
---
From manual page: https://php.net/function.abs
---
The manual says that the abs() function accepts 1 argument of the type "mixed", but
enabling strict_types and passing a string to the abs function outputs an type error.
Test script:
---------------
<?php
declare(strict_types=1);
$a = "0.00";
var_dump(abs($a));
Expected result:
----------------
In php 7 it would output:
float(0)
Actual result:
--------------
Fatal error: Uncaught TypeError: abs(): Argument #1 ($num) must be of type int|float, string given
in /in/ZD7Kd:7
Stack trace:
#0 /in/ZD7Kd(7): abs('0.00')
#1 {main}
thrown in /in/ZD7Kd on line 7
