  • Remove the equivalence with real+imag*1j which can be incorrect in corner
    cases (non-finite numbers, the sign of zeroes).
  • Separately document the three roles of the constructor: parsing a string,
    converting a number, and constructing a complex from components.
  • Document positional-only parameters of complex(), float(), int() and bool()
    as positional-only.
  • Add examples for complex() and int().
  • Specify the grammar of the string for complex().
  • Improve the grammar of the string for float().
  • Describe more explicitly the behavior when real and/or imag arguments are
    complex numbers. (This will be deprecated in future.)
    (cherry picked from commit ec1ba26)
