Ah okay, what was meant in this ticket's description is GiNaC's implementation of the Nielsen Generalized Polylogarithm which is not in mpmath. I have changed the description accordingly.

    • Property Summary changed from numeric evaluation of polylog to implement Nielsen Generalized Polylogarithm
  • Ticket #10050 – Description

    v3 v5  
    1 Numeric evaluation methods for the `polylog` function are commented out in the pynac source since it tries to call the `CLN` library directly. The calls to CLN should be replaced with their MPFR, etc. equivalents.

     1Numeric evaluation methods for the Nielsen Generalized Polylogarithm are commented out in the pynac source since it tries to call the `CLN` library directly. The calls to CLN should be replaced with their MPFR, etc. equivalents and the function made available symbolically in Sage. The Pynac part is https://github.com/pynac/pynac/issues/3
