CEXP(3P)

💖 CEXP(3P) — complex exponential functions 💖

okay bestie, we're in the POSIX Programmer's Manual — that's the 3P in the corner, iykyk ✨

---

🌸 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 — so if you're on Linux, go consult the corresponding Linux manual page for the details of Linux behavior 👀. Or honestly? The interface might not even be implemented on Linux at all. Vibe check accordingly 💀

✨ NAME ✨

cexp, cexp, cexpl — wait no, let me not do my girl math on the function names 😭

cexp, cexpf, cexpl — the complex exponential functions 🦋

---

🎀 SYNOPSIS 🎀

#include <complex.h>

double complex cexp(double complex z);
float complex cexpf(float complex z);
long double complex cexpl(long double complex z);

three flavors, one vibe: double, float, long double. pick your precision, queen 👑

💅 DESCRIPTION 💅

The functionality described on this reference page is aligned with the ISO C standard. And if there's any conflict between what's written here and the ISO C standard? That is unintentional, fr fr — this volume of POSIX.1‐2017 defers to the ISO C standard. periodt.

These functions shall compute the complex exponent of z, defined as e^z. iconic behavior, honestly 🫶

---

🔥 RETURN VALUE 🔥

These functions shall return the complex exponential value of z. That's the whole gig. no notes 💖

---

💀 ERRORS 💀

No errors are defined. not me being like "no thoughts head empty" but make it a spec 😭

heads up bestie: the sections that follow are informative — so they're the chill, non-normative part of the page ✨

---

🍓 EXAMPLES 🍓

None. the void, the emptiness, the audacity 🙈

---

🌈 APPLICATION USAGE 🌈

None. she said nothing and she meant it 💅

---

🧚 RATIONALE 🧚

None. no reasoning given, no reasoning needed, main character energy 👑

---

⭐ FUTURE DIRECTIONS ⭐

None. the future is unspecified and honestly? freeing 🦋

and that's the whole page, bestie!! this one's from IEEE/The Open Group, dated 2017, and it lives at CEXP(3P) 🎀 go forth and exponentiate your complexes, you absolute legend 💖✨🌸
