Unfortunately, it seems that I'm not allowed to copy paste the parts of the HyperSpec that detail the branch cuts.
Could somebody with a tiny little spare time create LaTeX snippets containing the essential parts of the information from the HyperSpec, eg. HyperSpec/Body/f_asin_.htm It should be roughly as follows: The Common Lisp standard defines singularities and branch cuts of asin in terms of those of log and sqrt via asin z = -i log (iz+sqrt(1-z^2)) branch cuts for asin are: * along the negative real axis to the left of -1 (inclusive), continuous with quadrant II, * along the positive real axis to the right of 1 (inclusive), continuous with quadrant IV. The range contains the complex numbers with * real part strictly between -<PI>/2 and <PI>/2, * real part equal to -<PI>/2 and non-negative imaginary part * real part equal to <PI>/2 and non-positive imaginary part. I hope that this is legal. We really need to include these in the docstrings of ELEMFUN, I think.
