[GiNaC-list] Min/Max functions

Hi everyone, I'm currently evaluating whether to use GiNaC for my project where I basically need to differentiate functions containing max(…,…), some tanh(…), and some other atrocities. Now, from the documentation it looks like GiNaC does not implement max() or min(). I realize that these functions do weird things (especially when you differentiate them). Still, I was wondering if they are really not included, just missing from the documentation, or if I'm too blind to find them. Any pointers are appreciated! Regards, Lukas
