This PR

  • adds support for complex number subtraction. Complex number subtraction is well-defined, where (a + bj) - (c + dj) = (a+bj) + (-(c+dj)) = (a+bj)+(-c-dj) = (a-c) + (c-d)j.
  • Specifies that special cases are defined according to complex number addition.
  • updates the input and output array data types to be any numeric data type, not just real-valued data types.
  • this PR depends on gh-525.
