Operations

At the beginning of the course, we used the * operator to demonstrate multiplication and we use the / operator for division.

Division remainder​

The remainder operator % can also be used to return the division remainder.

Here's an example,

4 % 2; // Division remainder is 0
9 % 2; // Division remainder is 1

  • The division remainder of 8 % 2 is calculated as follows:

    8 / 2 = 4 => the division remainder is 0 because 8 = 4 * 2 + 0

  • In the case of 7 % 2:

    7 / 2 = 3 (rounded) => the division remainder is 1 because 7 = 3 * 2 + 1.

In two chapters, we'll use the division remainder to determine whether a number is even or odd.
