casinh, casinhf—complex arc hyperbolic sineSynopsis
#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
