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;
