std::unifor...distribution(3)

💖 std::unifor...distribution(3) 💖

okay so bestie, welcome to the C++ Standard Libary manual page for std::unifor...distribution(3) — and yes, we're keeping that exact spelling, periodt. This page is all about the std::uniform_real_distribution::uniform_real_distribution constructor, and it's giving "let me construct a new distribution object for u" energy. 💅✨

---

🌸 NAME 🌸

std::uniform_real_distribution::uniform_real_distribution — std::uniform_real_distribution::uniform_real_distribution

That's the constructor name, repeated exactly like the original, no cap. 🫶

---

🦋 Synopsis 🦋

lowkey the whole synopsis is right here, bestie — copy it exactly, don't touch the RealType:

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

Constructs a new distribution object.

2. Uses a and b as the distribution parameters.
3. Uses params as the distribution parameters.

---

✨ Parameters ✨

• a — the a distribution parameter (minimum value).
• b — the b distribution parameter (maximum value).
• params — the distribution parameter set.

---

🫶 Notes 🫶

Requires that a ≤ b and b - a ≤ std::numeric_limits<RealType>::max().

bestie, if a == b, subsequent calls to the operator() overload that does not accept a param_type object will cause undefined behavior. That's not a vibe check you wanna fail. 💀

To create a distribution over the closed interval [a,b], std::nextafter(b, std::numeric_limits<RealType>::max()) may be used as the second parameter.

🎀 Defect reports 🎀

The following behavior-changing defect reports were applied retroactively to previously published C++ standards.

The columns are DR, Applied to, Behavior as published, and Correct behavior:

• P0935R0 — applied to C++11; behavior as published: default constructor was explicit; correct behavior: made implicit.
