The conceptions connected with a branching of functions into linear subfunctions is generalized for branchings of special kind functions into the transformations having a prescribed sign. Characteristic estimations for branchings of the functions realized by the generators "$\delta$–$\tau$ steps" and with alternating step are obtained.
Keywords: branching degree, sign in semigroup, "$\delta$–$\tau$ steps" generator, generator with alternating step.
