Abstract: We compute the analogue for $ {\mathbf{Z}}[i]$ of Euler's constant, that is $ \delta = {\lim _{n \to + \infty }}{\delta _n}$, where $ {\delta _n} = ({\Sigma _{2 \leqslant k \leqslant n}}1/\pi r_k^2) - \log n$. For this purpose we give an estimate for

$\displaystyle {r_k} = \min \left\{ {r \geqslant 0;{\text{there exists}}\;z \in ... ...\text{such that card}}({\mathbf{Z}}[i] \cap \bar D(z,r)) \geqslant k} \right\},$

and we compute a great number of values of $ {r_k}$.
