These functions shall compute the complex arc tangent of
z, with branch
cuts outside the interval [-
i, +
i] along the imaginary
axis.
These functions shall return the complex arc tangent value, in the range of a
strip mathematically unbounded along the imaginary axis and in the interval
[-pi/2, +pi/2] along the real axis.
