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.
