The modulus (remainder) operator is represented by a percent sign (%) and is used in the following way:
var result = 26 % 5; //equal to 1
The modulus operator behaves differently for special values, as follows:
| Operand | Result |
|---|---|
| If the operands are numbers | regular arithmetic division is performed, and the remainder is returned. |
| If the dividend is an infinite number and the divisor is a finite number | the result is NaN. |
| If the dividend is a finite number and the divisor is 0 | the result is NaN. |
| If Infinity is divided by Infinity | the result is NaN. |
| If the dividend is a finite number and the divisor is an infinite number | the result is the dividend. |
| If the dividend is zero and the divisor is nonzero | the result is zero. |
| If either operand isn't a number | it is converted to a number behind the scenes using Number() and then the other rules are applied. |
