The case of PauliStrings outside the Pauli group, i.e. with coefficients not in {1, -1, i, -i} may render a long ugly floating point number. Perhaps add explicit format string, e.g. limiting to three or four decimal places.

Cover the case outside the Pauli group, e.g. cirq.PauliString({a: cirq.X}, coefficient=np.sqrt(1j)).
