✨ FECLEAREXCEPT ✨

okay bestie, welcome to the POSIX Programmer's Manual page for feclearexcept — the little function that says "mmm, no thanks" to your floating-point exceptions 💅

🫶 PROLOG

so real talk before we even get into it: this manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ (consult the corresponding Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux at all 😭. iykyk.

💖 NAME

feclearexcept — clear floating-point exception

like, she clears them. that's her whole job. iconic.

🌸 SYNOPSIS

#include <fenv.h>

int feclearexcept(int excepts);

🦋 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 — fr fr, no drama intended. This volume of POSIX.1‐2017 defers to the ISO C standard.

So what does she do? The feclearexcept() function shall attempt to clear the supported floating-point exceptions represented by excepts.

that's it. that's the whole vibe. you hand her a mask of exceptions via excepts, she tries to wipe them. main character energy, honestly.

🎀 RETURN VALUE

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

💅 ERRORS

No errors are defined. not one. zero. she doesn't do errors.
