23 The functionality described on this reference page is aligned with the
24 ISO C standard. Any conflict between the requirements described here
25 and the ISO C standard is unintentional. This volume of POSIX.1‐2008
26 defers to the ISO C standard.

28 These functions shall compute the complex arc hyperbolic sine of z,
29 with branch cuts outside the interval [−i, +i] along the imaginary
30 axis.
31
33 These functions shall return the complex arc hyperbolic sine value, in
34 the range of a strip mathematically unbounded along the real axis and
35 in the interval [−iπ/2, +iπ/2] along the imaginary axis.
