  • Just take a look: if this is 9, 5 divided by 9 is always going to be 0 point something, and if you thus have two integers and you're rounding down, which is what happens when you do integral math we're using this operator, I'm going to get zero times whatever.

    稍微看一看:如果这是9,5除以9会得到,0点几,如果你用两个整型数,你舍去小数,这就是当你们,用整型数使用这个操作的所发生的事情,我将得到数值0乘以任何一个数字。
