Thanks,
Another one (always with complex.fs included):

0e 0e 0e 0e z** z. NaNai  ok

it must be 1 ( tested with python, julia and matlab)

and
0e 0e 1e 0e z** z. NaNai  ok, it must be 0

in general, with gforth: 0e 0e (a+bi) z** gives false results,
it must give 0e when (a+bi)<>0e.

So the definition of z** also must be revised.

All my respect.
