Cephes Mathematical Functions Library

See the master branch for the original google-deepmind/torch-cephes.

This project was used only to obtain the original Cephes Math Library reference output. Therefore, contributions regarding precision and error-related contributions are not accepted.

Tip

For general use please use scipy/xsf instead, which is a header-only library containing a modernized (C++17) refactoring of the classic AMOS/SPECFUN/Cephes/... special function implementations.
