πŸ’– CASINH(3POSIX) πŸ’–

okay bestie, so this one's from the POSIX Programmer's Manual β€” CASINH, that's the complex arc hyperbolic sine situation. Let's get into it πŸ¦‹

✨ PROLOG ✨

so like, real talk first: this manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ β€” which means if you're on Linux you lowkey gotta consult the corresponding Linux manual page for details of Linux behavior. OR, plot twist, the interface may not even be implemented on Linux at all. πŸ™ˆ vibe check accordingly.

🌸 NAME 🌸

casinh, casinhf, casinhl β€” complex arc hyperbolic sine functions. yes queen, three of them, one family πŸ’…

🌈 SYNOPSIS 🌈

#include <complex.h>

double complex casinh(double complex z);
float complex casinhf(float complex z);
long double complex casinhl(long double complex z);

πŸŽ€ DESCRIPTION πŸŽ€

The functionality described on this reference page is aligned with the ISO C standard. And like, if there's any conflict between the requirements described here and the ISO C standard, that's not intentional, fr fr β€” this volume of POSIX.1‐2017 defers to the ISO C standard. periodt.

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

⭐ RETURN VALUE ⭐

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 [-iΟ€/2, +iΟ€/2] along the imaginary axis. so real axis: go wild, no bounds πŸ’€. imaginary axis: you're living between -iΟ€/2 and +iΟ€/2, no exceptions bestie.

πŸ’€ ERRORS πŸ’€

No errors are defined.

okay that's the whole page bestie, we ate and left no crumbs 🍽️✨ IEEE/The Open Group, 2017 β€” CASINH(3POSIX) πŸ’– bye ily, go compute some complex arc hyperbolic sines responsibly πŸ¦‹
