💖 NAME 💖

okay bestie, welcome to the std::poisso...bution::mean(3) page from the C++ Standard Libary manual — and the NAME line is literally giving “same name twice” energy: std::poisson_distribution::mean - std::poisson_distribution::mean ✨. No cap, that’s the whole name vibe.

✨ Synopsis ✨

Here’s the signature, copied exactly:

okay so what does it do? It returns the μ parameter the distribution was constructed with 💅. That parameter defines the mean number of occurrences of the event. The default value is 1.0. Periodt.

🎀 Parameters 🎀
