**Abstract.**It is defined a representation system for numbers in the unit interval, generalising the dyadic one, and two dynamical systems are given which generate it. Metric results are especially derived from the second of them. The approximative coefficient
is defined and studied with this second dynamical system. Moreover, it is deduced that, among other results, the Jager pair
has the same distribution on a set of -measure 1, it is concentrated on a denumerable set of segments in
and an explicit expression is given for it.

In addition, Gauss-Kuzmin-Levy and Limit Central Theorem type results are given for some random variables in connection with this representation numbers system.
