在 JavaScript 中，你也可以用小数进行计算，就像整数一样。
|
|
|
|
把两个小数相乘，并得到它们乘积。
|

改变`0.0`的数值让变量`product`的值等于`5.0`。
|
|
|
|
# --hints--
|
|
|
|
变量`product`应该等于`5.0`。
|
|
|
|
```js
|
|
assert(product === 5.0);
|
|
```
|
|
|
|
要使用`*`运算符。
|
|
|
|
```js
|
|
assert(/\*/.test(code));
|
|
```
|

(function(y){return 'product = '+y;})(product);
|

```
