Thank you for your interest and for perusing the article.

A quote from the article: "Tanh-Sinh C source code derived from the WP-34S Tanh-Sinh Python code (MIT licensed)". There is also a Visual Basic version "Tanh-Sinh V5.0 VB QUAD_TANH_SINH source code" in the article with "The full RPN source code for the WP 34S calculator integration program was written by M. César Rodríguez in 2017". The article lists a version of the WP34s code in C, but does not state that the WP34s code was originally written in C. The C version represents the WP34s code.
