CACOS(3P) πŸ’–

okay bestie, so this is the POSIX Programmer's Manual page for cacos, cacosf, and cacosl β€” the complex arc cosine girlies πŸ’… like, the group chat version, yes, but the manual name is real and it's CACOS(3P), section 3P, POSIX Programmer's Manual. Periodt.

✨ PROLOG

Not me having to say this first, but: this manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ (so like, go consult the corresponding Linux manual page for the deets on Linux behavior, fr fr), or honestly the interface may not even be implemented on Linux at all. πŸ™ˆ

πŸŽ€ NAME

cacos, cacosf, cacosl β€” complex arc cosine functions πŸ¦‹

⭐ SYNOPSIS

#include <complex.h>

double complex cacos(double complex z);
float complex cacosf(float complex z);
long double complex cacosl(long double complex z);

three functions, three precisions, one vibe. iconic behavior honestly. πŸ‘‘

🌸 DESCRIPTION

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 β€” like, no drama intended, bestie. This volume of POSIX.1-2017 defers to the ISO C standard.

These functions shall compute the complex arc cosine of z, with branch cuts outside the interval [-1, +1] along the real axis. that's the whole thing. that's the job. 🫢

πŸ’– RETURN VALUE

These functions shall return the complex arc cosine value, in the range of a strip that is mathematically unbounded along the imaginary axis and in the interval [0, Ο€] along the real axis. so like β€” imaginary axis? no ceiling. real axis? cozy between 0 and Ο€. πŸ’«

😭 ERRORS

No errors are defined.

also bestie, heads up: the following sections are informative. so don't come for them like they're normative, okay? they're just vibing. ✨
