This PR

  • adds complex number support to acosh by documenting special cases. By convention, the inverse hyperbolic cosine has a branch cut placed at the line segment (-infinity, 1) of the real axis.
  • updates the input and output array data types to be any floating-point data type, not just real-valued floating-point data types.
  • derives special cases from C99
