STD::EXTREME_VALUE_DISTRIBUTION(3)

✨ std::extreme_value_distribution< _RealType > ✨

okay bestie, sit down, hydrate, and let's talk about a random number distribution — this whole page lives in the libstdc++ Library Functions Manual, section 3, and it's genuinely so much. 💖

🎀 NAME 🎀

std::extreme_value_distribution< _RealType > — bestie it is literally "A extreme_value_distribution random number distribution." that's the whole vibe, that's the name. 🦋

🌸 SYNOPSIS 🌸

#include <random>

💅 Classes 💅

• struct param_type

🫶 Public Types 🫶

• typedef _RealType result_type

✨ Public Member Functions ✨

• extreme_value_distribution (_RealType __a, _RealType __b=_RealType(1)) — constructor, and yes the __b default is _RealType(1), look at her go 💫
• extreme_value_distribution (const param_type &__p) — constructor but make it a parameter-set girlie
• template<typename _ForwardIterator, typename _UniformRandomNumberGenerator> void __generate (_ForwardIterator __f, _ForwardIterator __t, _UniformRandomNumberGenerator &__urng) — the generate-y one
• template<typename _ForwardIterator, typename _UniformRandomNumberGenerator> void __generate (_ForwardIterator __f, _ForwardIterator __t, _UniformRandomNumberGenerator &__urng, const param_type &__p) — same energy but now with a param_type passed in, no cap
• template<typename _UniformRandomNumberGenerator> void __generate (result_type *__f, result_type *__t, _UniformRandomNumberGenerator &__urng, const param_type &__p) — pointer-flavoured __generate, iconic
• _RealType a () const — Return the $a$ parameter of the distribution.
• _RealType b () const — Return the $b$ parameter of the distribution.
• result_type max () const — Returns the least upper bound value of the distribution.
• result_type min () const — Returns the greatest lower bound value of the distribution.
• template<typename _UniformRandomNumberGenerator> result_type operator() (_UniformRandomNumberGenerator &__urng) — Generating functions.
• template<typename _UniformRandomNumberGenerator> result_type operator() (_UniformRandomNumberGenerator &__urng, const param_type &__p) — the other generating function, she's right there
• param_type param () const — Returns the parameter set of the distribution.
• void param (const param_type &__param) — Sets the parameter set of the distribution.
• void reset () — Resets the distribution state.

🍓 Friends 🍓

• bool operator== (const extreme_value_distribution &__d1, const extreme_value_distribution &__d2) — Return true if two extreme value distributions have the same parameters.

🌈 Detailed Description 🌈

template<typename _RealType = double>
    class std::extreme_value_distribution< _RealType >

"A extreme_value_distribution random number distribution." that's her, that's the girl 💜

The formula for the normal probability mass function is, and I'm quoting this exactly because it's a whole moment:

p(x|a,b) =
ac{1}{b}
               \xp( ac{a-x}{b} - \xp(ac{a-x}{b})) ]

Since — C++11 ✨ (yes she's been around, she's vintage-adjacent, she's a legend for it)
