Fix pushed to the master branch, as commit c09d63e. Thanks!

I'm going to look into what's the case for 'tan'. For 'tan',
tan(pi/4)=tan(45°) is rational as well - I'm going to look into
whether the 'S' of 'tan' is only the integer multiples pi/4, or
whether there are more.
It's only those:
For which θ is θ/π and tan(θ) rational?
Assume t=tan(θ)∈ℚ. Not

One more thing: arctan2. Can be implemented in terms of arctan, but
getting the sign right is inconvenient.
This revised patch documents the limitations of this module and adds more unit
tests.
I've also changed the functions to short-circuit only results that are
rational, since
the exactness property is already lost in any case when the square roots are
irrational.

Belated thank you :-)
