FECLEAREXCEPT(3P)

🦋 FECLEAREXCEPT(3P) — POSIX Programmer's Manual 🦋

okay bestie, welcome to the POSIX Programmer's Manual, we're doing feclearpexcept today and it's lowkey one of the most chill functions in <fenv.h>. 💖

🌸 PROLOG 🌸

Real talk before we start: 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 peek at the corresponding Linux manual page for the actual tea on Linux behavior. Or, plot twist, the interface may not be implemented on Linux at all. 🙈

✨ NAME ✨

feclearpexcept — clear floating-point exception

(yeah that's it, that's the whole name, she's simple and she's iconic 💅)

---

🎀 SYNOPSIS 🎀

#include <fenv.h>

int feclearexcept(int excepts);

---

💖 DESCRIPTION 💖

So the functionality described on this reference page is aligned with the ISO C standard. And like, if there's any conflict between the requirements described here and the ISO C standard? That's unintentional, fr fr. This volume of POSIX.1‐2017 defers to the ISO C standard. ISO C is the main character here, we're just supporting cast. 👑

Now the actual function, the moment you've been waiting for:

The feclearpexcept() function shall attempt to clear the supported floating-point exceptions represented by excepts.

That's it. That's the whole vibe. It attempts. It's giving "I'll try my best." 🫶

---

⭐ RETURN VALUE ⭐

• If the argument is zero — or if all the specified exceptions were successfully cleared — feclearpexcept() shall return zero. Slay. ✨
• Otherwise, it shall return a non-zero value. 😭

no cap, that copyright section is long but we do not skip a single word of it, bestie. every detail stays. periodt. 💖

okay and that's the whole page!! this one came from IEEE/The Open Group, 2017, and the manual name is FECLEAREXCEPT(3P) in case you forgot — which you didn't, because you're a genius. go clear some floating-point exceptions, you absolute icon. 🎀✨
