[issue22548] Bogus parsing of negative zeros in complex literals

[Mark Dickinson]

Mark Dickinson added the comment:

Sorry; that should be:

  complex(-0.0, 0.0) - complex(0.0, 0.0)

The imaginary part is then worked out as (0.0 - 0.0), which (in all rounding modes but round-towards-negative) is 0.0.
