casinh, casinhf, casinhl - complex arc hyperbolic sine functions
c99 [ flag... ] file... –lm [ library... ] #include <complex.h> 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 [ −iπ/2, +iπ/2 ] along the imaginary axis.
