Defined in header <ratio>
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.

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

Member functions

operator bool
converts the object to bool, returns value

[edit]Example

#include <ratio>   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>>);}
