Návod, kniha: POSIX Programmer's Manual
double complex cacosh(double complex z);
float complex cacoshf(float complex z);
long double complex cacoshl(long double complex z);
These functions shall compute the complex arc hyperbolic cosine of z
with a branch cut at values less than 1 along the real axis.
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 [- i
pi] along the imaginary axis.
No errors are defined.
