< cpp‎ | numeric‎ | ratio
Defined in header <ratio>
template< class R1, class R2 >
struct ratio_greater : std::integral_constant;

If the ratio R1 is greater than than the ratio R2, provides the member constant value equal true. Otherwise, value is false.

Helper variable template

template< class R1, class R2 >
inline constexpr bool ratio_greater_v = ratio_greater<R1, R2>::value;
(since C++17)

Inherited from std::integral_constant

Member constants

true if R1::num * R2::den > R2::num * R1::den, or equivalent expression that avoids overflow , false otherwise
(public static member constant)

Member functions
