DESCRIPTION

22       These  functions  compute  the  complex arc sine of z, with branch cuts
23       outside the interval [ −1, +1 ] along the real axis.
24

RETURN VALUES

26       These functions return the complex arc sine value, in the  range  of  a
27       strip  mathematically  unbounded  along  the  imaginary axis and in the
28       interval [ −pi/2, +pi/2 ] along the real axis.
