std::extrem...::operator()(3)

💅 NAME 💅

okay so welcome to the std::extrem...::operator()(3) page from the C++ Standard Libary 💅 this one is all about std::extreme_value_distribution::operator() — and the NAME line is literally std::extreme_value_distribution::operator() - std::extreme_value_distribution::operator(). yes bestie, it said the same thing twice, and we are keeping it because facts are facts, periodt.

✨ Synopsis ✨

both overloads are template< class Generator > and both are since C++11 — vintage-ish but still slaying. here's the exact shape:

template< class Generator >                                       (1)
(since C++11)
result_type operator()( Generator& g );
template< class Generator >                                       (2)
(since C++11)
result_type operator()( Generator& g, const param_type& params );

this generates random numbers that are distributed according to the associated probability function. the entropy is acquired by calling g.operator() — that's the whole vibe.

version (1) uses the associated parameter set, and version (2) uses params. the associated parameter set is not modified — like, it stays exactly as it was, no cap 🫶.

🌸 Parameters 🌸

• g — a uniform random bit generator object. that's your entropy source, iykyk.
• params — distribution parameter set to use instead of the associated one.

🎀 Type requirements 🎀

• Generator must meet the requirements of UniformRandomBitGenerator. that's the vibe check it has to pass, fr fr.

🦋 Return value 🦋

the generated random number. that's it, that's the return 💖.

🔥 Complexity 🔥

amortized constant number of invocations of g.operator(). so like, constant-ish on average — the manpage says amortized constant, and we respect it 👑.
