Pour ceux qui veulent faire des tests poussés pour comprendre plus facilement toutes ces suites de 0 et de 1, j'avais posté une fonction sur le forum codée fraîchement par moi-même :

stock printBinary(value)
{
    new
        strv[33],
        str[66];
       
    format(strv, sizeof(strv), "%032b", value);
   
    for(new i = 0, j = 0, bool:v = true; i < sizeof(str); i++)
    {
        switch(i)
        {
            case 0, 16, 32, 48, 64: str[i] = '|', v = true;
            default: str[i] = v ? strv[j++] : ' ', v = !v;
        }
    }
 
    print(!"+---------------+---------------+---------------+---------------+");
    print(str);
    print(!"+---------------+---------------+---------------+---------------+");
   
    print(!" ");
}

 

Hexadécimal :

main()
{
	printBinary(0xF);
	printBinary(0xFF);
	printBinary(0xFFF);
	printBinary(0xFFFF);
	printBinary(0xFFFFF);
	printBinary(0xFFFFFF);
	printBinary(0xFFFFFFF);
	printBinary(0xFFFFFFFF);
}

 

Décimal :

main()
{
	printBinary(15);
	printBinary(255);
	printBinary(4095);
	printBinary(65535);
	printBinary(1048575);
	printBinary(16777215);
	printBinary(268435455);
	printBinary(-1);
}

 

Résultat dans les deux cas :

+---------------+---------------+---------------+---------------+
