roff source from the Linux documentation project. Modifications before import: -added NetBSD RCS ID -removed Linux PROLOG and declarations with "long double" -ran the "deshallify" script as required by The Open Group Split out complex related things into an own Makefile fragment. Thanks to hubertf for directions.

.SH DESCRIPTION
|
|
.LP
|
|
These functions compute the complex arc cosine of \fIz\fP, with
|
|
branch cuts outside the interval [-1,\ +1] along the
|
|
real axis.
|
|
.SH RETURN VALUE
|
|
.LP
|
|
These functions return the complex arc cosine value, in the
|
|
range of a strip mathematically unbounded along the imaginary
|
|
axis and in the interval [0,\ pi] along the real axis.
