CIMAG(3P)

📦 version 2017a, in alpine 3.22, alpine 3.23, alpine 3.24, arch rolling, nixpkgs unstable, opensuse-leap 16.0

💖 PROLOG 💖

ok so bestie, heads up: this manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ (so like, go check the corresponding Linux manual page for the deets on Linux behavior), or honestly the interface might not even be implemented on Linux at all. 🙈

✨ NAME ✨

cimag, cimagf, cimagl — the complex imaginary functions, aka the girls who pull the imaginary part out of your complex number 💅

🌸 SYNOPSIS 🌸

#include <complex.h>

double cimag(double complex z);
float cimagf(float complex z);
long double cimagl(long double complex z);

🦋 DESCRIPTION 🦋

Okay so first thing, bestie: 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. periodt.

These functions shall compute the imaginary part of z. That's it. That's the whole job. And they ate. 🔥

👑 RETURN VALUE 👑

These functions shall return the imaginary part value — as a real. no cap.

💀 ERRORS 💀

No errors are defined. literally none. she's flawless. ✨

The following sections are informative.

🍓 EXAMPLES 🍓

None. (yeah i know, the silence is loud 😭)

🧚 APPLICATION USAGE 🧚

For a variable z of complex type:

z == creal(z) + cimag(z)*I

that's the vibe check right there. imaginary part times I, real part on its own, they add up to z. iykyk 💜

🌈 RATIONALE 🌈

None.

⭐ FUTURE DIRECTIONS ⭐

None.
