We compute numerically the distribution of energies $\Omega(E,N)$ for the XY--model with short--range and long--range interactions. We find that in both cases the distribution can be fitted to the functional form: $\Omega(E,N)\sim \exp(N \phi(E,N))$, with $\phi(E,N)$ an intensive function of the energy.
