casinh, casinhf, casinhl — complex arc hyperbolic sine functions

  #include <complex.h>
  double complex casinh(double complex z);
  float complex casinhf(float complex z);
  long double complex casinhl(long double complex z);

The functionality described on this reference page is aligned with the ISO C standard. Any conflict between the requirements described here and the ISO C standard is unintentional. This volume of POSIX.1‐2017 defers to the ISO C standard.

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

These functions shall return the complex arc hyperbolic sine value, in the range of a strip mathematically unbounded along the real axis and in the interval [-/i/π/2, +/i/π/2] along the imaginary axis.
