.SH DESCRIPTION
19
.LP
20
These functions shall compute the complex arc sine of \fIz\fP, with
21
branch cuts outside the interval [-1,\ +1] along the
22
real axis.
23
.SH RETURN VALUE
24
.LP
25
These functions shall return the complex arc sine value, in the range
26
of a strip mathematically unbounded along the imaginary
27
axis and in the interval [-pi/2,\ +pi/2] along the
28
real axis.
