Polylogarithm 7.0.0

New

• added install target to export the C/C++/Fortran libraries
• added examples to the examples/ directory
• source code coverage report

Fixes

• Proper treatment of arguments with signed zero for all functions (PR #37)
• Fixed imprecision of all complex polylogarithms for small arguments (PR #39)

Polylogarithm 6.15.0

New

• single-precision implementation of real and complex li2.

Changes

• extended range of all complex polylogarithms that do not cause a floating-point overflow

Polylogarithm 6.14.0

Changes

• use log1p(x) instead of log(1 + x) to avoid a potential catastrophic cancellation (has not been observed)
• remove unnecessary calls of std::abs and fabs
• replace std::pow(2.0, n - 1) by std::exp2(n - 1) which is faster on some systems
• update doctest.h to 2.4.9
