Why does the following function not work as intended? It seems like the
test for N being even doesn't work :(

pow(N,0) -> io:write({pow,N,0}), io:nl(), 1;
pow(N,2) -> N * N;
pow(N,1) -> N;
pow(N,M) when N rem 2 == 0 ->
  io:write({powNeven,N,M}), io:nl(),
  X = pow(N,M div 2), X * X.

28> test:pow(10,3).
