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. |
