  24. .SH DESCRIPTION
  25. The functionality described on this reference page is aligned with the
  26. ISO\ C standard. Any conflict between the requirements described here and the
  27. ISO\ C standard is unintentional. This volume of POSIX.1\(hy2017 defers to the ISO\ C standard.

  29. These functions shall compute the complex arc hyperbolic sine of
  30. .IR z ,
  31. with branch cuts outside the interval [\-\fIi\fR,\ +\fIi\fR] along
  32. the imaginary axis.
  33. .SH "RETURN VALUE"
  34. These functions shall return the complex arc hyperbolic sine value, in
  35. the range of a strip mathematically unbounded along the real axis and
  36. in the interval [\-\fIi\fR\(*p/2,\ +\fIi\fR\(*p/2] along the
  37. imaginary axis.
