DESCRIPTION

22       These  functions  compute the complex arc cosine of z, with branch cuts
23       outside the interval [ -1, +1 ] along the real axis.
24

RETURN VALUES

26       These functions return the complex arc cosine value, in the range of  a
27       strip  mathematically  unbounded  along  the  imaginary axis and in the
28       interval  [ 0, pi ] along the real axis.
