ERAND48(3POSIX)

💖 ERAND48 — the POSIX Programmer's Manual one 💖

okay bestie, real talk: this page lives inside the POSIX Programmer's Manual, that's its whole home base. but heads up — the Linux implementation of this interface may be different from what's written here, so if you're on Linux, go peek at the corresponding Linux manual page for the actual tea. and lowkey? the interface might not even be implemented on Linux at all. 🙈 so vibe check first, code later.

✨ PROLOG ✨

so this manual page is part of the POSIX Programmer's Manual. that's the lore. 🎀

but the Linux implementation of this interface may differ — consult the corresponding Linux manual page for the details of Linux behavior. or, plot twist, the interface may not be implemented on Linux. it's giving "maybe, maybe not" and honestly? iconic. 💅

🌸 NAME 🌸

erand48 — generate uniformly distributed pseudo-random numbers

yes bestie, random numbers. uniformly distributed ones. the good stuff. ✨

🦋 SYNOPSIS 🦋

#include <stdlib.h>

double erand48(unsigned short xsubi[3]);

look at that little signature. she's short, she's sweet, she takes an array of three unsigned shorts and she gives you back a double. periodt. 💜

👑 DESCRIPTION 👑

Refer to drand48().

that's it. that's the whole description. she's a delegator, she's got main character energy, and she is NOT explaining herself twice. go read drand48(). iykyk. 💀
