Abstract. This paper contains a formal presentation of the construction of Real Numbers as proposed
by various authors some years ago. One insists in presenting this mathematical work in a systematic
fashion inherited from the usage of formal methods in system modeling. This work is a preparation for
a complete mechanized development with a theorem prover. This work was done in 2012 and proved
using Rodin in 2021 in the EBRP project. Some (little) errors are detected and corrected during the
proof
