okay bestie, welcome to the POSIX Programmer's Manual page for cacosh β€” yes the whole squad: cacosh, cacoshf, cacoshl. Complex arc hyperbolic cosine, but make it ✨fabulous✨. Let's get into it πŸ¦‹

🌸 PROLOG 🌸

This manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ (consult the corresponding Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux.

ngl that's the standard "your mileage may vary" disclaimer, and it applies fr fr. Check the Linux page if you're on Linux. πŸ’…

πŸ‘‘ NAME πŸ‘‘

cacosh, cacoshf, cacoshl β€” complex arc hyperbolic cosine functions

✨ SYNOPSIS ✨

#include <complex.h>

double complex cacosh(double complex z);
float complex cacoshf(float complex z);
long double complex cacoshl(long double complex z);

πŸ’œ DESCRIPTION πŸ’œ

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 cosine of z, with a branch cut at values less than 1 along the real axis.

branch cut at values less than 1 on the real axis β€” that's the drama zone, okay? Noted. πŸŽ€

🫢 RETURN VALUE 🫢

These functions shall return the complex arc hyperbolic cosine value, in the range of a half-strip of non-negative values along the real axis and in the interval [-iΟ€, +iΟ€] along the imaginary axis.
