Can someone describe what the modulus operator is, I don't understand it.

Question

none

Answer 1

As long as you know what division is... you know what modulus (modulo reduction) is. Think of it like this...

11 divided by 5 is 2, with a remainder of 1. (5 * 2 + 1 = 11)

or..

13 divided by 7 is 1, with a remainder of 6. (7 * 1 + 6 = 13)

basically, just divide the numbers wherever you see the modulus operator, and the remainder will be the answer.

Answer 2

5 divided by 2 results in 2 with remainder of 1.
You can read 5 % 2 as five modulus 2, or the remainder when 5 is divided by two.

Hence,

5 modulus 2 is 1.

More examples:

5%3 = 2
11%5 = 1
12%11 = 1
1%2 = 1

Answer 3

Modulus cannot be greater than the divisor

Answer 4

Is what's left on a division, also called reminder

For example 15/15 = 1 (Modulo 0)

Another example is 5/3 = 1.6 (modulo 2)

6/3 = 2 (Modulo= 0)

Answer 5

Thank you. Makes so much sense now. I got caught up with the percent sign.

Answer 6

Modulo is the remainder.
