Имя (Name)
casinh, casinhf, casinhl — complex arc hyperbolic sine functions
Синопсис (Synopsis)
#include <complex.h>
double complex casinh(double complex z);
float complex casinhf(float complex z);
long double complex casinhl(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 sine of
z, with branch cuts outside the interval [-i, +i] along the
imaginary axis.
Возвращаемое значение (Return value)
These functions shall return the complex arc hyperbolic sine
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.
