ABS(3P)

💖 ABS(3P) — bestie edition 💖

okay so welcome to the POSIX Programmer's Manual, the abs page, and honestly? it's a short one. a little snack. a lil' bite-sized baddie. but we're still gonna do it right. no skipping. let's go 🫶

---

✨ PROLOG

heads up, bestie: this manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ — so consult the corresponding Linux manual page for details on Linux behavior — or, plot twist, the interface may not be implemented on Linux at all. 😭

---

🌸 NAME

abs — return an integer absolute value. that's it. that's the whole job. iconic behavior honestly ✨

---

🎀 SYNOPSIS

#include <stdlib.h>

int abs(int i);

look at her. so clean. so simple. main character energy 🦋

---

💅 DESCRIPTION

so, 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? that conflict is unintentional, fr fr. This volume of POSIX.1‐2017 defers to the ISO C standard. respect the hierarchy, periodt. 👑

The abs() function shall compute the absolute value of its integer operand, i. 💖

okay but listen — if the result cannot be represented, the behavior is undefined. undefined behavior is NOT cute, bestie. it's giving chaos. do not do this to yourself. 💀

---

⭐ RETURN VALUE

The abs() function shall return the absolute value of its integer operand. like, that's the whole vibe check. in goes i, out comes the abs. 🎀

---

🙈 ERRORS

No errors are defined. she simply does not have problems. mentally stable queen. ✨

The following sections are informative — i.e. the vibes-only section, not the requirements section. iykyk.

---

🌈 EXAMPLES

None. 💀

(sorry bestie. no examples. she's a minimalist. we respect it. 🫶)

---

🧚 APPLICATION USAGE

okay this one matters, so lean in 👑

In two's-complement representation, the absolute value of the negative integer with the largest magnitude, {INT_MIN}, might not be representable. 😭

so like — that one specific value is out here living its truth and abs() literally cannot return it. be careful with that one. that's the drama. that's the whole drama. 💅

---

💜 RATIONALE

None. 🎀

(nothing to justify. she just is. iconic.)

---

🦋 FUTURE DIRECTIONS

None. ⭐

(future? she's timeless.)

go read those too, bestie, they're in the same friend group 🫶
