double complex casinh(double complex z);
float complex casinhf(float complex z);
long double complex casinhl(long double complex z);
These functions compute the complex arc hyperbolic sine of z, with branch cuts outside the interval [ -i, +i] along the imaginary axis.
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 [ -ipi/2, +ipi/2 ] along the imaginary axis.
