casinh
, casinhf
—complex arc hyperbolic sine#include <complex.h> double complex casinh(double complex z); float complex casinhf(float complex z);
Description
These functions compute the complex arc hyperbolic sine of z,
with branch cuts outside the interval [-i, +i] along the
imaginary axis.
casinhf
is identical to casinh
, except that it performs
its calculations on floats complex
.
Returns
These functions return the complex arc hyperbolic sine value,
in the range of a strip mathematically unbounded along the
real axis and in the interval [-i*p/2, +i*p/2] along the
imaginary axis.
Portability
casinh
and casinhf
are ISO C99
