# --description--
|
|
|
|
The <dfn>remainder</dfn> operator `%` gives the remainder of the division of two numbers.
|
|
|
|
**Example**
|
|
|
|
<pre>
|
|
5 % 2 = 1
|
|
5 / 2 = 2 remainder 1
|
|
2 * 2 = 4
|
|
5 - 4 = 1
|
|
</pre>
|
|
|
|
**Usage**
|
|
In mathematics, a number can be checked to be even or odd by checking the remainder of the division of the number by `2`. Even numbers have a remainder of `0`, while odd numbers a remainder of `1`.
|
|
|
|
<pre>
|
|
17 % 2 = 1
|
|
48 % 2 = 0
|
|
</pre>
|
|
|
|
**Note:** The <dfn>remainder</dfn> operator is sometimes incorrectly referred to as the modulus operator. It is very similar to modulus, but does not work properly with negative numbers.
|
|
|
|
# --instructions--
|
|
|
|
Set `remainder` equal to the remainder of `11` divided by `3` using the <dfn>remainder</dfn> (`%`) operator.
|
|
|
|
# --hints--
|
|
|
|
The variable `remainder` should be initialized
|
|
|
|
```js
|
|
assert(/(const|let|var)\s+?remainder/.test(code));
|
|
```
|
|
|
|
The value of `remainder` should be `2`
|
|
|
|
```js
|
|
assert(remainder === 2);
|
|
```
|
|
|
|
You should use the `%` operator
|
|
|
|
```js
|
|
assert(/\s+?remainder\s*?=\s*?.*%.*;?/.test(code));
|
|
```
|
|
|
|
# --seed--
|
|
|
|
## --after-user-code--
|
|
|
|
```js
|
|
(function (y) {
|
|
return 'remainder = ' + y;
|
|
})(remainder);
|
|
```
|
|
|
|
## --seed-contents--
|
|
|
|
```js
|
|
const remainder = 0;
|
|
```
|
|
|
|
# --solutions--
|
|
|
|
```js
|
|
const remainder = 11 % 3;
|
|
```
