💖 CONJ(3POSIX) 💖

okay bestie, so this is the POSIX Programmer's Manual page for conj — and it's literally serving IEEE/The Open Group energy from 2017. Pull up a chair, we're about to make complex conjugates make sense 🫶

✨ PROLOG ✨

okay so real talk first, this is a POSIX Programmer's Manual page, periodt. That means the Linux implementation of this interface may differ — so if you're on Linux, go check the corresponding Linux manual page for the actual details of Linux behavior. Or, plot twist, the interface might not even be implemented on Linux at all 🙈 no cap.

🎀 NAME 🎀

conj, conjf, conjl — the complex conjugate functions 💅

🌸 SYNOPSIS 🌸

#include <complex.h>

double complex conj(double complex z);
float complex conjf(float complex z);
long double complex conjl(long double complex z);

🦋 DESCRIPTION 🦋

So the functionality described on this reference page is aligned with the ISO C standard. If there's any conflict between what's written here and the ISO C standard, that's unintentional — like, not on purpose at all. This volume of POSIX.1-2017 defers to the ISO C standard. Periodt.

These functions shall compute the complex conjugate of z, by reversing the sign of its imaginary part. That's it. That's the whole job. Iconic, honestly 👑

⭐ RETURN VALUE ⭐

These functions return the complex conjugate value. Simple as that 💜

🔥 ERRORS 🔥

No errors are defined. None. Zero. The error list is empty, she's not coming to the function today 😌

The following sections are informative. (iykyk — that means they're the extra lore, not the binding rules)

🍓 EXAMPLES 🍓

None. Bestie really said "figure it out" 💀

🧚 APPLICATION USAGE 🧚

None. Nada. Nothing here, moving on 🌈

💫 RATIONALE 💫

None. No rationale given, the vibes are simply the rationale ✨

🎀 FUTURE DIRECTIONS 🎀

None. The future is unwritten and also this section is empty 🦋

and that's the whole page, bestie 💖 this was IEEE/The Open Group, 2017, signing off — stay conjugated, stay iconic, and go reverse a sign or two for me 🌸✨🫶
