Имя (Name)
cacos, cacosf, cacosl — complex arc cosine functions
Синопсис (Synopsis)
#include <complex.h>
double complex cacos(double complex z);
float complex cacosf(float complex z);
long double complex cacosl(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 cosine 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 cosine value, in the
range of a strip mathematically unbounded along the imaginary
axis and in the interval [0, π] along the real axis.
