.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. |
