💖 FMIN(3P) — the girlies' guide to POSIX Programmer's Manual 💖

okay bestie, so this page lives in the POSIX Programmer's Manual — that's the manual name, we're not copying the header line, iykyk ✨

🫶 PROLOG 🫶

So here's the tea: this manual page is literally part of the POSIX Programmer's Manual. But lowkey, the Linux implementation of this interface may differ — so if you're on Linux, consult the corresponding Linux manual page for the deets on Linux behavior. OR, plot twist, the interface may not be implemented on Linux at all. 😭 vibe check accordingly.

🌸 NAME 🌸

fmin, fminf, fminl — determine minimum numeric value of two floating-point numbers

✨ SYNOPSIS ✨

#include <math.h>

double fmin(double x, double y);
float fminf(float x, float y);
long double fminl(long double x, long double y);

💅 DESCRIPTION 💅

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? Not intentional, bestie, we promise. 🙈 This volume of POSIX.1‐2017 defers to the ISO C standard.

These functions shall determine the minimum numeric value of their arguments.

Now here's the iconic part: NaN arguments shall be treated as missing data — so if one argument is a NaN and the other one is numeric, then these functions shall choose the numeric value. the way that works is honestly so main character of them. 👑

🔥 RETURN VALUE 🔥

Upon successful completion, these functions shall return the minimum numeric value of their arguments.

  • If just one argument is a NaN, the other argument shall be returned. 🦋
  • If x and y are both NaN, a NaN shall be returned. 💀

🎀 ERRORS 🎀

No errors are defined. periodt.

The following sections are informative — so like, they're giving bonus content, not requirements. 💜

okay that's the whole page bestie, every single crumb of it, nothing skipped, we ate and left no crumbs 💅✨

so yeah — this one's from IEEE/The Open Group, 2017, and it's page FMIN(3P). go forth and fmin responsibly, queen 🫶🌸
