The anomalous magnetic moment g-2 of lepton is one of the most closely studied quantities in particle physics. The electron g-2 has played the central role in testing the validity of quantum electrodynamics (QED). The notable discrepancy observed between the measurement and the theoretical prediction of the muon g-2 may lead to a possible new physics beyond the standard model. Recent updates in the QED contribution involving the complete determination of the tenth-order correction in the perturbation theory provides further improvements in the precision tests. Our numerical approach toward these problems is described.
