💖 std::uniform_real_distribution< _RealType > 💖

okay so bestie, welcome to the Library Functions Manual, section 3, and this page is literally called std::uniform_real_distribution< _RealType >(3). it's giving random numbers, it's giving C++ <random> energy, and we're gonna go through every single thing on it together, no skipping, periodt. 🎀

✨ NAME ✨

std::uniform_real_distribution< _RealType > — Uniform continuous distribution for random numbers.

that's it. that's the whole name. iconic, honestly. 💅

🌸 SYNOPSIS 🌸

#include <random>

🫶 Classes

  • struct param_type — it's here! the page lists it and gives us zero extra description, so we simply respect the mystery. 🙈

🦋 Public Types

  • typedef _RealType result_type — the type of the range of the distribution, aka the flavour of number you're gonna be pulling out of this thing. ⭐

👑 Public Member Functions

  • uniform_real_distribution () — Constructs a uniform_real_distribution object.
  • uniform_real_distribution (_RealType __a, _RealType __b=_RealType(1)) — Constructs a uniform_real_distribution object.
  • uniform_real_distribution (const param_type &__p) — constructs one from a param_type, and yes we are listing it because it is on the page. 😌
  • template<typename _ForwardIterator, typename _UniformRandomNumberGenerator> void __generate (_ForwardIterator __f, _ForwardIterator __t, _UniformRandomNumberGenerator &__urng) — it's there, it's templated, we copy it exactly, no notes.
  • template<typename _ForwardIterator, typename _UniformRandomNumberGenerator> void __generate (_ForwardIterator __f, _ForwardIterator __t, _UniformRandomNumberGenerator &__urng, const param_type &__p) — same situation, now with a param_type in the mix.
  • template<typename _UniformRandomNumberGenerator> void __generate (result_type *__f, result_type *__t, _UniformRandomNumberGenerator &__urng, const param_type &__p) — the pointer-flavoured one, still exact, still here.
  • result_type a () const — on the list. that's the assignment. 💜
  • result_type b () const — also on the list. matching set, cute.
  • result_type max () const — Returns the inclusive upper bound of the distribution range.
  • result_type min () const — Returns the inclusive lower bound of the distribution range.
  • template<typename _UniformRandomNumberGenerator> result_type operator() (_UniformRandomNumberGenerator &__urng) — Generating functions.
  • template<typename _UniformRandomNumberGenerator> result_type operator() (_UniformRandomNumberGenerator &__urng, const param_type &__p) — the two-argument sibling, sitting right below it like it belongs there (it does).
  • 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 uniform_real_distribution &__d1, const uniform_real_distribution &__d2) — Return true if two uniform real distributions have the same parameters.

🔥 Detailed Description 🔥

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

"Uniform continuous distribution for random numbers."

A continuous random distribution on the range [min, max) with equal probability throughout the range. The URNG should be real-valued and deliver number in the range [0, 1).

Since: C++11

bestie, clock the range notation: it's [min, max) — square bracket on the left, round bracket on the right. that means the top end is not included. do not come for me, that's what the page says. 😭

⭐ Member Typedef Documentation ⭐

template<typename _RealType = double> typedef _RealType
    std::uniform_real_distribution< _RealType >::result_type

The type of the range of the distribution.

🧚 Constructor & Destructor Documentation 🧚

template<typename _RealType = double> std::uniform_real_distribution< _RealType >::uniform_real_distribution () [inline]

Constructs a uniform_real_distribution object. The lower bound is set to 0.0 and the upper bound to 1.0

template<typename _RealType = double> std::uniform_real_distribution< _RealType >::uniform_real_distribution (_RealType __a, _RealType __b = _RealType(1)) [inline], [explicit]

Constructs a uniform_real_distribution object.

Parameters

  • __a [IN] — The lower bound of the distribution.
  • __b [IN] — The upper bound of the distribution.
it's marked [explicit], bestie, so no sneaky implicit conversions. respect the boundary. 💅

💜 Member Function Documentation 💜

template<typename _RealType = double> result_type std::uniform_real_distribution< _RealType >::max () const [inline]

Returns the inclusive upper bound of the distribution range.

template<typename _RealType = double> result_type std::uniform_real_distribution< _RealType >::min () const [inline]

Returns the inclusive lower bound of the distribution range.

template<typename _RealType = double> template<typename _UniformRandomNumberGenerator> result_type std::uniform_real_distribution< _RealType >::operator() (_UniformRandomNumberGenerator & __urng) [inline]

Generating functions.

Referenced by operator()().

template<typename _RealType = double> param_type std::uniform_real_distribution< _RealType >::param () const [inline]

Returns the parameter set of the distribution.

Referenced by std::operator>>().

template<typename _RealType = double> void std::uniform_real_distribution< _RealType >::param (const param_type & __param) [inline]

Sets the parameter set of the distribution.

Parameters

  • __param — The new parameter set of the distribution.

template<typename _RealType = double> void std::uniform_real_distribution< _RealType >::reset () [inline]

Resets the distribution state. Does nothing for the uniform real distribution.

not the reset () doing absolutely nothing for this distribution 😭 honestly? relatable. sometimes the most productive thing you can do is nothing. self-care king. 🌸

template<typename _RealType = double> bool operator== (const uniform_real_distribution< _RealType > & __d1, const uniform_real_distribution< _RealType > & __d2) [friend]

Return true if two uniform real distributions have the same parameters.

so yeah. it's auto-generated, it's libstdc++, and nobody hand-wrote this — the robots did it and they ate. 👑

okay that's the whole page, bestie, every single line accounted for, nothing skipped, nothing invented. this was libstdc++ bringing you the Library Functions Manual entry for std::unifo..._RealType >(3) — go forth and generate some floats, love u, byeee 💖✨🌈
