DESCRIPTION

22       These  functions compute the complex arc hyperbolic cosine of z, with a
23       branch cut at values less than 1 along the real axis.
24

RETURN VALUES

26       These functions return the complex arc hyperbolic cosine value, in  the
27       range of a half-strip of non-negative values along the real axis and in
28       the interval [ -ipi, +ipi ] along the imaginary axis.
