NAMEcasinh, casinhf, casinhl - complex arc sine hyperbolic
double complex casinh(double complex z);
float complex casinhf(float complex z);
long double complex casinhl(long double complex z);
DESCRIPTIONThe casinh() function calculates the complex arc hyperbolic sine of z. If y = casinh(z), then z = csinh(y). The imaginary part of y is chosen in the interval [-pi/2,pi/2].
casinh(z) = clog(z + csqrt(z * z + 1))
VERSIONSThese functions first appeared in glibc in version 2.1.
