Summary: Here we combine the ideas of a quantum functional theory intended to describe intrinsically extended particles with those of a geometrostochastic one describing stochastically extended particles. The main ingredients of the former are a physical wave $$u$$ replacing the point $$x$$ and a functional wave $$X[u, t]$$ replacing the probability wave function of the conventional quantum theory. The latter introduces a proper wave function accounting for the unavoidable errors in the measurement of continuous observable such as the position and momentum.
