PHP 按位取反的问题
现在有一串数字,
$str=1300022332121
要求按位取反该怎么弄
这个按位取反,跟其他程序的按位取反,有不同之处吗
因为我是要能够将他传给C++写的程序的,
请各位大侠执教

PHP code
$str=1300022332121;
echo ~$str; //2147483647

没有那么简单<br><br>你的C++要求传入的是什么?<br><br>1300022332121 已经超出了 unsigned long 可表示的范围了 <div class="clear">
                 
              
              
        
            </div>
Copy after login
