std::expone...distribution(3)

💖 NAME 💖

okay so this page is std::expone...distribution(3) from the C++ Standard Libary manual — yes, that's literally how the header spells it, bestie 😭 — and the thing it's naming is std::exponential_distribution::exponential_distribution, the constructor. The NAME line is extra and repeats it like this: std::exponential_distribution::exponential_distribution - std::exponential_distribution::exponential_distribution. slay.

✨ Synopsis ✨

          exponential_distribution() : exponential_distribution(1.0) {}  (1)
       (since C++11)
          explicit exponential_distribution( RealType lambda );          (2)
       (since C++11)
          explicit exponential_distribution( const param_type& params ); (3)
       (since C++11)

Constructs a new distribution object. 2) Uses lambda as the distribution parameter. 3) Uses params as the distribution parameter.

🌸 Parameters 🌸

• lambda — the λ distribution parameter (the rate parameter)
• params — the distribution parameter set

🎀 Notes 🎀

⚠️ Requires that 0 < lambda.
