That's the modulus operator.

Also called "modulo" or "remainder", the modulus operator performs a division operation but instead of returning the result it returns the remainder. For example, 12 % 7 = 5 because if you divide 12 by 7 the result is 1 but you have 5 left over. For expression evaluation, it has the same precedence as the multiply and divide operators.

Hi there! The % sign is used as the modulus/modulo operator. This operator returns the remainder of the division of the 2 numbers. For example, in this case, the 8 % 5 would return a 3. This is because 8 is divisible by 5 with a remainder of 3. Eight divided by five is equal to 1 and 3/5. The three here is the remainder.

Hope this helps! :sparkles:

Ok thanks I understand now
