Duh. It is. It's

What gave you the idea it wasn't representable in binary? All even numbers
can be represented in binary. (Most odd numbers can, too. Exceptions are
the powers of three... actually, more generally, the only odd numbers that
can be represented base two are those that are also multiples of some power
of two, so they can be converted over.)
