NAME
       std::ratio -

       Provides compile-time rational arithmetic.

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

   Static Public Attributes
       static const intmax_t den
       static const 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;
