# --description--

现在让我们将一个小数除以另一个小数。

# --instructions--

改变数值`0.0`的值让变量`quotient`的值等于`2.2`.

# --hints--

`quotient`的值应该等于`2.2`。

```js
assert(quotient === 2.2);
```

使用`/`运算符将 4.4 除以 2。

```js
assert(/4\.40*\s*\/\s*2\.*0*/.test(code));
```

quotient 变量应该只被赋值一次。

```js
assert(code.match(/quotient/g).length === 1);
```

# --seed--

## --after-user-code--

```js
(function(y){return 'quotient = '+y;})(quotient);
```

## --seed-contents--

```js
var quotient = 0.0 / 2.0; // Change this line
```

# --solutions--

```js
var quotient = 4.4 / 2.0;
```
