💖 IMAXABS(3P) 💖

okay bestie, gather round — this is the IMAXABS(3P) page from the POSIX Programmer's Manual, and we're gonna make it make sense. 🎀

🚨 PROLOG 🚨

Real talk first, no cap: this manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ — so if you're on Linux, go check the corresponding Linux manual page for the actual tea on Linux behavior ☕. And also? The interface may not be implemented on Linux at all. iykyk 💅

✨ NAME ✨

imaxabs — return absolute value 🦋

---

🌸 SYNOPSIS 🌸

#include <inttypes.h>

intmax_t imaxabs(intmax_t j);

there she is. the whole entire function. gorgeous. 💜

---

💅 DESCRIPTION 💅

Okay so the functionality described on this reference page is aligned with the ISO C standard. And like — any conflict between the requirements described here and the ISO C standard is unintentional, okay?? 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.

⚠️ But listen — if the result cannot be represented, the behavior is UNDEFINED. Not "kinda weird", not "implementation-defined", undefined. That's the scary one, bestie. 😭

---

🫶 RETURN VALUE 🫶

The imaxabs() function shall return the absolute value. that's it. that's the return value. iconic behavior honestly. ⭐

---

💀 ERRORS 💀

No errors are defined. None. Zero. Nada. the error list is empty, she's at peace 🧘

The following sections are informative. (aka: the chill, non-normative part of the page, lowkey just vibes 🌈)

---

🍓 EXAMPLES 🍓

None. we have no examples to show you and we are not sorry about it 🙈

---

🎀 APPLICATION USAGE 🎀

Here's the important bit, so pay attention bestie: the absolute value of the most negative number cannot be represented in two's complement. So like, that number is out here being its own unrepresentable self. 💀 math is wild fr fr.

---

🧚 RATIONALE 🧚

None. no thoughts, head empty, no rationale 🦋

---

⭐ FUTURE DIRECTIONS ⭐

None. the future is bright and contains zero future directions ✨
