CASINH(3)                  Library Functions Manual                  CASINH(3)

NAME
     casinh, casinhf, casinhl -- complex arc hyperbolic sine functions

SYNOPSIS
     #include <complex.h>

     double complex
     casinh(double complex z);

     float complex
     casinhf(float complex z);

     long double complex
     casinhl(long double complex z);

DESCRIPTION
     These functions compute the complex arc hyperbolic sine of z, with branch
     cuts outside the interval [-i, +i] along the imaginary axis.

RETURN VALUES
     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 [-i pi/2, +i pi/2] along the imaginary axis.

ERRORS
     No errors are defined.
