| 2. 12. 1. Modulus (%) |
|
|
Modulus (%) operator returns only the remainder. |
If either value is a string, an attempt is made to convert the string to a number. |
For example, the following line of code |
|
var resultOfMod = 26 % 3;
|
|
would result in the remainder of 2 being stored in the variable resultOfMod. |

The modulus operator behaves differently for special values: |
- If the operands are numbers, regular arithmetic division is performed, and the remainder of that division is returned.
- If the dividend is Infinity or the divisor is 0, the result is NaN.
- If Infinity is divided by Infinity, the result is NaN.
- If the divisor is an infinite number, the result is the dividend.
- If the dividend is 0, the result is 0.
