20 These functions compute the complex arc hyperbolic cosine of
22 with a branch cut at values less than 1 along the real axis.
24 These functions return the complex arc hyperbolic cosine value,
25 in the range of a half-strip of non-negative values along
26 the real axis and in the interval [\-i pi,\ +i pi] along
