On $q$-deformed real numbers

Abstract

We associate a formal power series with integer coefficients to a positive real number, we interpret this series as a "qq-analogue of a real." The construction is based on the notion of qq-deformed rational number introduced in arXiv:1812.00170. Extending the construction to negative real numbers, we obtain certain Laurent series.
