Detailed Description
template<intmax_t _Num, intmax_t _Den = 1>
struct std::ratio< _Num, _Den >"Provides compile-time rational arithmetic.
This class template represents any finite rational number with a numerator and denominator representable by compile-time constants of type intmax_t. The ratio is simplified when instantiated.
For example:
std::ratio<7,-21>::num == -1; std::ratio<7,-21>::den == 3;
