std::cauchy...distribution(3)

💖 NAME 💖

std::cauchy_distribution::cauchy_distribution — ok so this is the constructor of cauchy_distribution, straight outta the C++ Standard Library (that's the manual this page lives in, bestie). It's literally the same name twice because constructors are like that. 💅

✨ Synopsis ✨

   cauchy_distribution() : cauchy_distribution(0.0) {}           (1)
(since C++11)
   explicit cauchy_distribution( RealType a, RealType b = 1.0 ); (2)
(since C++11)
   explicit cauchy_distribution( const param_type& params );     (3)
(since C++11)

So there's three flavors of this icon, and every single one of them has been around (since C++11) — vintage but still slaying. 🫶

🌸 DESCRIPTION 🌸

Constructs a new distribution object. That's the whole vibe — you're making a fresh cauchy_distribution. 🦋

1. Number (1) is the default one, and it just delegates: cauchy_distribution() : cauchy_distribution(0.0) {}.
2. Number (2) uses a and b as the distribution parameters.
3. Number (3) uses params as the distribution parameters.

🎀 PARAMETERS 🎀

• a — the a distribution parameter, aka the location. 📍
• b — the b distribution parameter, aka the scale. 📏
• params — the distribution parameter set. 🍓

💅 Defect reports 💅

The following behavior-changing defect reports were applied retroactively to previously published C++ standards. Not me reading the patch notes retroactively 😭 — yes, they went back and fixed old standards, periodt.

• P0935R0 — applied to C++11 — behavior as published: the default constructor was explicit; correct behavior: made implicit. So if you were out here treating it like it needed an explicit cast, that's the glow-up right there. ✨

ngl the explicit → implicit thing is the whole drama of this page, and it's giving "we fixed it after the fact" energy. Keep it in mind if you're reading ancient C++11-era code, bestie. 💀

And that's a wrap, iykyk 🌈 — this lil page came from http://cppreference.com, dated 2024.06.10, and it's the std::cauchy...distribution(3) manual page. Go construct something iconic. 👑💜
