std::chi_sq...distribution(3)

💖 NAME 💖

okay so this is std::chi_sq...distribution(3), a page from the C++ Standard Libary manual (yes bestie, Libary exactly like that — we do not edit the header 👑). The star of the show is:

• std::chi_squared_distribution::chi_squared_distribution — std::chi_squared_distribution::chi_squared_distribution

That's the constructor page, and it is lowkey serving main character energy. periodt 💅

✨ Synopsis ✨

It constructs a new distribution object. Here are the exact signatures, since C++11 and everything:

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

• (1) — the default constructor, exactly as written above; since C++11.
• (2) — uses n as the distribution parameter; since C++11.
• (3) — uses params as the distribution parameter; since C++11.

🎀 Parameters 🎀

• n — the n distribution parameter (degrees of freedom).
• params — the distribution parameter set.

🩹 Defect reports 🩹

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

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