_余数运算符_ `%`给出了两个数的除法的余数。
|
|||
|
|
|
|||
|
|
## 例
|
|||
|
|
```
|
|||
|
|
5 % 2 = 1 because
|
|||
|
|
Math.floor(5 / 2) = 2 (Quotient)
|
|||
|
|
2 * 2 = 4
|
|||
|
|
5 - 4 = 1 (Remainder)
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
## 用法
|
|||
|
|
|
|||
|
|
在数学中，通过检查数字除法的余数为2，可以检查偶数或奇数。
|
|||
|
|
```
|
|||
|
|
17 % 2 = 1 (17 is Odd)
|
|||
|
|
48 % 2 = 0 (48 is Even)
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
**注意**不要将它与_模数_ `%`混淆，否则与负数不兼容。
