The evaluation of the truncation error coefficient Qn introduced by MOLODENSKII et al. requires generally a complicated mathematicalprocess especially at high degrees, if we want to obtain accurate values of Qn The author presents a practical approximation formula which can be used of evaluate Qn at high degrees with a sufficient accuracy for the practical\purpose and to decrease computer time drasti cally.
