.SH DESCRIPTION
|
|
.LP
|
|
These functions compute the complex arc sine 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 sine value, in the range
|
|
of a strip mathematically unbounded along the imaginary
|
|
axis and in the interval [-pi/2,\ +pi/2] along the
|
|
real axis.
