NAME
       std::ratio< _Num, _Den > -

SYNOPSIS
   Public Types
       typedef ratio< num, den > type

   Public Member Functions
       static_assert (_Den!=0,'denominator cannot be zero')
       static_assert (_Num >=-__INTMAX_MAX__ &&_Den >=-__INTMAX_MAX__,'out of range')

   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;
