These functions shall compute the complex arc hyperbolic cosine of
z,
with a branch cut at values less than 1 along the real axis.
These functions shall return the complex arc hyperbolic cosine value, in the
range of a half-strip of non-negative values along the real axis and in the
interval [-
ipi, +
ipi] along the imaginary axis.
