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;
