Detailed Description

template<intmax_t N, intmax_t D = 1>
class std::ratio< N, D >

A compile-time ratio of two integers, automatically reduced to lowest terms.

Template Parameters

N	The unreduced numerator of the ratio
D	The unreduced denominator of the ratio

Precondition

The denominator must not be 0, and both numerator and denominator must have representable absolute values
