We wrote this code years ago and it is not currently maintained. I guess expf is (was ?) part of the stl but is no longer exposed from the same headers since some version of the compiler ? I don't even remember if we were using g++ or clang, that tells you something 😆

Anyways, I have absolutely no time to dedicate to this project anymore, so beside this hint you are on your own ¯_(ツ)_/¯
