NAME casinh, casinhf, casinhl - complex arc sine hyperbolic
SYNOPSIS #include <complex.h> double complex casinh(double complex z); float complex casinhf(float complex z); long double complex casinhl(long double complex z); Link with -lm.
DESCRIPTION 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]. One has: casinh(z) = clog(z + csqrt(z * z + 1))
VERSIONS These functions first appeared in glibc in version 2.1.
