✨ CSQRT(3POSIX) ✨

okay so bestie, welcome to the POSIX Programmer's Manual 💖 — this page lives in the POSIX Programmer's Manual, and it's giving very much "read the fine print" energy.

💅 PROLOG

okay so real talk first 🫶 this manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ (so like, pls consult the corresponding Linux manual page for the deets on Linux behavior), or the interface might not even be implemented on Linux at all. 💀 no cap.

👑 NAME

csqrt, csqrtf, csqrtl — complex square root functions ✨

🌸 SYNOPSIS

#include <complex.h>

double complex csqrt(double complex z);
float complex csqrtf(float complex z);
long double complex csqrtl(long double complex z);

🦋 DESCRIPTION

The functionality described on this reference page is aligned with the ISO C standard. And listen — any conflict between the requirements described here and the ISO C standard is unintentional, like nobody's trying to start drama. This volume of POSIX.1‐2017 defers to the ISO C standard. periodt.

These functions shall compute the complex square root of z, with a branch cut along the negative real axis. 🌈 (yes the branch cut is the moment, iykyk)

💖 RETURN VALUE

These functions shall return the complex square root value, in the range of the right half-plane (including the imaginary axis). slay. 💅

🎀 ERRORS

No errors are defined. not a single one. iconic behavior honestly.

None. 🙈 (yes really, nothing)

🧚 APPLICATION USAGE

⭐ RATIONALE

None. ✨

🔥 FUTURE DIRECTIONS

okay that's the whole page bestie, tysm for reading, mwah 💖 — this lil beauty comes to you from IEEE/The Open Group, dated 2017, and it's the CSQRT(3POSIX) page. take care of her, she's doing her best 🎀✨
