NAME

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

SYNOPSIS

   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.

       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;
