Hi, we are about the implement a dilogarithm function in MPFR. Looking at the different definitions, it seems the GSL definition is not the "standard" one in the Abramowitz&Stegun sense, but more what is commonly designed as Li2(x) [as the GSL manual admits it].
This is quite annoying, since if we introduce a function mpfr_dilog in MPFR, it will be either inconsistent with A&S, or inconsistent with GSL, and in both cases will probably confuse the users. One solution would be for us to only export a function mpfr_li2, which would correspond to the "common" definition of Li2(x), and to the gsl_sf_dilog function. Would that be ok for you? Can you explain why you choosed that mathematical definition for gsl_sf_dilog, or that name instead of gsl_sf_li2? Best regards, Paul Zimmermann (for the MPFR developers) _______________________________________________ Help-gsl mailing list [email protected] http://lists.gnu.org/mailman/listinfo/help-gsl
