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.
answer = 7 % 2;
document.write("answer = ",answer);
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.
