This paper deals with the asymptotic behavior of the integral $$ I_\alpha(t)=\int_1^t \psi_\alpha(\xi)\,d\xi, \qquad\text{where}\quad \psi_\alpha(t)=\min_{1\le q\le t}\|q\alpha\| $$ (here the minimum is taken over integers $q$ and $\|\,\cdot\,\|$ denotes the distance to the nearest integer).
Keywords: real number, measure of irrationality, continued fraction
Mots-clés : convergent, Lebesgue measure, Gauss transformation, ergodic transformation.
