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;
