casinh, 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);
Link with -lm.
These functions calculate 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))
These functions first appeared in glibc in version 2.1.
For an explanation of the terms used in this section, see attributes(7).
