Синопсис (Synopsis)

Описание (Description)

The functionality described on this reference page is aligned
       with the ISO C standard. Any conflict between the requirements
       described here and the ISO C standard is unintentional. This
       volume of POSIX.1‐2017 defers to the ISO C standard.

       These functions shall compute the complex arc hyperbolic tangent
       of z, with branch cuts outside the interval [-1, +1] along the
       real axis.

---

Возвращаемое значение (Return value)

These functions shall return the complex arc hyperbolic tangent
       value, in the range of a strip mathematically unbounded along the
       real axis and in the interval [-iπ/2, +iπ/2] along the imaginary
       axis.
