如果我想要得到真正的除法答案，我需要把他们之中的一个，变为浮点数类型。

If I wanted to get full, real division, I should make one of them a float.

所以这里的意思是编译器将,做“计算“，譬如13这样一个浮点数,-到另一个浮点数-,然后为我们处理除法。

So what that means is the compiler is actually going to first "cast" so to speak 13 from whatever it is - to a float -- to a floating point value -- and then perform the division for us.
