💖 CPOW(3P) — POSIX Programmer's Manual 💖

okay bestie, so this one's from the POSIX Programmer's Manual and it's literally all about complex power functions. grab a snack, we're doing math 🍓

🌸 PROLOG 🌸

So like, heads up: this manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ — so if you're on Linux, go peek at the corresponding Linux manual page for the deets on how Linux actually behaves. Or… it might just not be implemented on Linux at all. 🙈 vibe check accordingly.

✨ NAME ✨

cpow, cpowf, cpowl — the complex power functions, i.e. the girlies who raise complex numbers to complex powers 👑

🎀 SYNOPSIS 🎀

#include <complex.h>

double complex cpow(double complex x, double complex y);
float complex cpowf(float complex x, float complex y);
long double complex cpowl(long double complex x,
    long double complex y);

🦋 DESCRIPTION 🦋

The functionality described on this reference page is aligned with the ISO C standard. And like, if there's any conflict between what's written here and the ISO C standard? Not intentional, fr fr. This volume of POSIX.1‐2017 defers to the ISO C standard, no cap.

These functions shall compute the complex power function x<sup>y</sup> — wait, okay, the original says it like xy but it means x to the y, the complex power function — and the important part: there's a branch cut for the first parameter along the negative real axis. Remember that, it matters. 💅

💜 RETURN VALUE 💜

These functions shall return the complex power function value. That's it, that's the tea. 🫶

🌈 ERRORS 🌈

No errors are defined. None. Zero. Not a single one. iconic behaviour honestly 😌

The following sections are informative.

🧚 EXAMPLES 🧚

None. (sad, I know — the original said so 😭)

⭐ APPLICATION USAGE ⭐

None. (again, blame the original, not me 💀)

🍓 RATIONALE 🍓

None.

🌸 FUTURE DIRECTIONS 🌸

None.

and that's the whole page, bestie — no notes, it's giving "short but mighty" 💖

okay bye ilysm, this was IEEE/The Open Group, 2017 — CPOW(3P), out 🎀✨
