Multiple of 3

Does anyone know how to check whether a number is a multiple of 3 without using arithmatic operators!!!!!!!
Thanks in advance!!!!

How could you do it without arithmetic operators; surely that's impossible?

Or are you meant to use bit-fiddling techniques?

I believe you use 'mod'.

For example

if( 15mod3 == 0 ) {

I think. Not sure.

EDIT* Actually on another post, I realise maybe instead of 'mod' it would be '%'

Don't you count the modulus operator '%' as an arithmetic operator then?
