Why is the exponential operator not implemented?

[simonnanty]

So far, you limited the implementation to a few operators (in https://github.com/marcovirgolin/gpg/blob/pybind/src/operator.hpp)

Is there a reason why the exponential is not one of them?

Would it be possible to add it?

[marcovirgolin]

Hi, no there is no specific reason to be honest, except that sometimes exp can be unruly out of domain.
But a PR that implements exp would be super welcome!
