如下代码
$qty = 50.852; echo (int) ($qty * 10000); // 期望结果:508520 // 实际结果:508519
以上问题如何解释？并且如何处理会得到期望结果？

原来的答案不对，删除，补充题目相关内容如下：
$qty = 50.852; echo $qty * 10000; //508520 echo (int) ($qty * 10000); //508519 echo round($qty * 10000); //508520 echo (int)($qty * 100000); //5085200 echo (int)($qty * 1000); //50852 echo (int)(508520); //508520 echo (int)50.852; //50
