Abstract

We consider the problem of estimating the possible number of periods and the length of the periodic part of an irrational number depending on its measure of irrationality β. We state that the expansion of the fractional part of an irrational number α cannot start with a nonperiodic part of length (1 − δ)N and cannot terminate with a periodic part of length δN, regardless of the numeral system.
