Имя (Name)
cacosh, cacoshf, cacoshl — complex arc hyperbolic cosine
functions
Синопсис (Synopsis)
#include <complex.h>
double complex cacosh(double complex z);
float complex cacoshf(float complex z);
long double complex cacoshl(long double complex z);
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 cosine
of z, with a branch cut at values less than 1 along the real
axis.
Возвращаемое значение (Return value)
These functions shall return the complex arc hyperbolic cosine
value, in the range of a half-strip of non-negative values along
the real axis and in the interval [-iπ, +iπ] along the imaginary
axis.
