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
