std::ratio_greater_equal - cppreference.com (original) (raw)

| | | | | ------------------------------------------------------------------------------------------------------------------------------------------------------------- | | ------------- | | template< class R1, class R2 > struct ratio_greater_equal : std::integral_constant<bool, /* see below */> { }; | | (since C++11) |

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

[edit] Helper variable template

| template< class R1, class R2 > constexpr bool ratio_greater_equal_v = ratio_greater_equal<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

| | converts the object to bool, returns value (public member function) | | ---------------------------------------------------------------------- | | | returns value (public member function) |

Member types

[edit] Example

#include   int main() { static_assert(std::ratio_greater_equal< std::ratio<2, 3>, std::ratio<2, 3>>::value, "2/3 >= 2/3");   // since C++17 static_assert(std::ratio_greater_equal_v< std::ratio<999'998, 999'999>, std::ratio<999'997, 999'998>>); }
