💖 `std::ratio< _Num, _Den >(3)` — Library Functions Manual 💖

okay bestie, welcome to the std::ratio< _Num, _Den >(3) page from the Library Functions Manual. it's giving compile-time math, and we're gonna get into it. ✨

🌸 NAME 🌸

std::ratio< _Num, _Den > - Provides compile-time rational arithmetic. 💅

🦋 SYNOPSIS 🦋

       #include <ratio>

✨ Public Types ✨

typedef ratio< num, den > type

🎀 Static Public Attributes 🎀

static constexpr intmax_t den
static constexpr intmax_t num

💅 Detailed Description 💅

   template<intmax_t _Num, intmax_t _Den = 1>
       struct std::ratio< _Num, _Den >"Provides compile-time rational
       arithmetic.

okay so this class template? it represents any finite rational number with a numerator and denominator representable by compile-time constants of type intmax_t. and the ratio is simplified when instantiated. no cap. 🔥

For example:

       std::ratio<7,-21>::num == -1;
       std::ratio<7,-21>::den == 3;

mwah 💋 this page is from libstdc++, and it's the std::ratio< _Num, _Den >(3) manual — the footer didn't give me a date, so that's the source/version and date situation, bestie. byeee 🦋
