Originální popis anglicky: catanh, catanhf, catanhl - complex arc hyperbolic tangent functions

Návod, kniha: POSIX Programmer's Manual

STRUČNĚ

#include <complex.h> double complex catanh(double complex z); float complex catanhf(float complex z); long double complex catanhl(long double complex z);

POPIS / INSTRUKCE

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

NÁVRATOVÁ HODNOTA

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 [- ipi/2, +ipi/2] along the imaginary axis.
