The C part of the source code has been changed only in mad_tpsa_fun.c adding a macro ("OLD_SERIES") and creating a new branch of code for the atan where I use my formula. I also had to add some auxiliary functions in mad_num.c for the double factorial and the hypretriangular numbers (specifically at line 178 num_t mad_num_dfact(int n) and line 192 num_t mad_num_HypTri(int d, int n)).
