  18 .SH DESCRIPTION
  19 .LP
  20 These functions shall compute the complex arc hyperbolic cosine of
  21 \fIz\fP, with a branch cut at values less than 1 along the
  22 real axis.
  23 .SH RETURN VALUE
  24 .LP
  25 These functions shall return the complex arc hyperbolic cosine value,
  26 in the range of a half-strip of non-negative values along
  27 the real axis and in the interval [-\fIi\fPpi,\ +\fIi\fPpi] along
  28 the imaginary axis.
