The two-dimensional discrete frustrated phi(4) model is studied by Monte Carlo simulations for two sets of the parameters of the model. Two phase transitions and a floating-incommensurate phase are observed for the case of stronger frustration. The phase transition from the floating-fluid phase to the floating - incommensurate phase is of Kosterlitz-Thouless type. A single phase transition from the floating-fluid phase to the ferro-phase is found for the case of weaker frustration.
