       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;

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