# --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;
```
