[Numpy-discussion] equal() and complex

[Mike R. <ro...@fs...>]

  I'm wondering if there is some good reason why equal(), not_equal(),
nonzero() and the like do not work with numeric arrays of tyep
complex.  I can see why operators like less() and less_equal() do not
work.  But the pure equality ones seem like they should work.  Or am I
missing something :).

Thanks,

Before Python 2.1, comparison couldn't be implemented for equality
only.
