title: Finding a Remainder in JavaScript
|
||
|
|
---
|
||
|
|
The _remainder operator_ `%` gives the remainder of the division of two numbers.
|
||
|
|
|
||
|
|
## Example
|
||
|
|
|
||
|
|
5 % 2 = 1 because
|
||
|
|
Math.floor(5 / 2) = 2 (Quotient)
|
||
|
|
2 * 2 = 4
|
||
|
|
5 - 4 = 1 (Remainder)
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
In mathematics, a number can be checked even or odd by checking the remainder of the division of the number by 2.
|
||
|
|
|
||
|
|
17 % 2 = 1 (17 is Odd)
|
||
|
|
48 % 2 = 0 (48 is Even)
|
||
|
|
|
||
|
|
**Note** Do not confuse it with _modulus_ `%` does not work well with negative numbers.
