std::ratio_greater_equal
From cppreference.com
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.

template<class R1, class R2 > constexprbool ratio_greater_equal_v = ratio_greater_equal<R1, R2>::value; | (since C++17) | |
Inherited from std::integral_constant
Member constants
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 (public member function) |
operator() (C++14) | returns value (public member function) |

[edit]Example
Run this code
#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>>);}
