Implementation of dilogarithm function for C++?

I've been looking through GSL and Boost libraries to find the dilogarithm function, but I have not found it.

Is there an implementation available for C++/C of this function?

Solution

  • GSL seems to have it: https://www.gnu.org/software/gsl/manual/html_node/Dilogarithm.html

    gsl_sf_dilog.h

    double gsl_sf_dilog (double x)
int gsl_sf_dilog_e (double x, gsl_sf_result * result)
int gsl_sf_complex_dilog_e (double r, double theta, gsl_sf_result * result_re, gsl_sf_result * result_im)
