double complex cacosh(double complex z);

These functions compute the complex arc hyperbolic cosine of z, with
a branch cut at values less than 1 along the real axis.
These functions 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.
No errors are defined.
