ArithmeticError

(PHP 7, PHP 8)

Introduction

ArithmeticError est lancée quand une erreur se produit lors d'une opération mathématique. Ces erreurs incluent les tentatives de réaliser un décalage de bits d'un montant négatif, n'importe quel appel à intdiv() qui donnerait lieu à une valeur en dehors des bornes possibles d'un entier.

the first example shifted by the positive number and the result is 4, but the second example shifted by the negative number and the result is ArithmeticError(this example is the same for left shift)
<?php

 $shif =1;
 $number = 8;
 $result =  $number >> $shif;
 echo $result; //// 1000 >> 01000 = 4

$shif =-1;
 $number = 8;
 $result =  $number >> $shif;
 ////result is ArithmeticError
?>
