IMAXABS(3POSIX)

📦 version 2017a, in debian bookworm, debian trixie, ubuntu jammy, ubuntu noble, ubuntu resolute, ubuntu stonking

💖 PROLOG 💖

ok so bestie, this manual page is part of the POSIX Programmer's Manual. but heads up 🫶 — 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 be implemented on Linux at all. vibe check your platform first, fr fr.

✨ NAME ✨

imaxabs — return absolute value 💅

🌸 SYNOPSIS 🌸

#include <inttypes.h>

intmax_t imaxabs(intmax_t j);

🦋 DESCRIPTION 🦋

okay so 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 — nobody's trying to start drama. this volume of POSIX.1‐2017 defers to the ISO C standard, periodt.

the imaxabs() function shall compute the absolute value of an integer j.

and if the result cannot be represented? the behavior is undefined. not "undefined-ish", not "we'll figure it out" — straight up undefined. do not test it, bestie 😭

🎀 RETURN VALUE 🎀

the imaxabs() function shall return the absolute value. that's it, that's the whole return value. iconic of it honestly 👑

💀 ERRORS 💀

no errors are defined. literally none. zero. not a single one.

the following sections are informative — like, they're here for the lore, not the rules.

🍓 EXAMPLES 🍓

None. 🧚 nothing to show, bestie, it's that simple.

🌈 APPLICATION USAGE 🌈

the absolute value of the most negative number cannot be represented in two's complement. so like… that one number? yeah, no abs for them. it's giving impossible 💀

⭐ RATIONALE ⭐

None. no reasoning was needed, it simply ate 🔥

🧚 FUTURE DIRECTIONS 🧚

None. this function is not going anywhere, she's staying exactly as she is 💜
