.. note::
For signed integer data types, the numerical negative of the minimum representable integer is implementation-dependent.

.. note::
If ``self`` has a complex floating-point data type, both the real and imaginary components for each ``self_i`` must be negated (a result which follows from the rules of complex number multiplication).

Parameters
----------
self: array
array instance. Should have a real-valued data type.
array instance. Should have a numeric data type.
