std::ratio_greater_equal(3)   C++ Standard Libary  std::ratio_greater_equal(3)

NAME
       std::ratio_greater_equal	- std::ratio_greater_equal

Synopsis
	  Defined in header <ratio>
	  template< class R1, class R2 >
	  struct  ratio_greater_equal  :  std::integral_constant<bool,	/* see
       (since C++11)
	  below	*/> { };

	  If the ratio R1 is greater than or equal to 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_equal_v     =	   ra-
       tio_greater_equal<R1,  (since C++17)
	  R2>::value;

       Inherited from std::integral_constant

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

Member functions
	  operator bool	converts the object to bool, returns value
			(public	member function)
	  operator()	returns	value
	  (C++14)	(public	member function)

Member types
	  Type	     Definition
	  value_type bool
	  type	     std::integral_constant<bool, value>

Example
       // Run this code

	#include <ratio>
	#include <iostream>

	auto main() -> int
	{
	    static_assert(std::ratio_greater_equal<
		std::ratio<2, 3>,
		std::ratio<2, 3>>::value, "2/3 >= 2/3");

	    if (std::ratio_greater_equal<
		std::ratio<2,1>, std::ratio<1, 2>>::value) {
		std::cout << "2/1 >= 1/2" "\n";
	    }

	    if (std::ratio_greater_equal<
		std::ratio<1,2>, std::ratio<1, 2>>::value) {
		std::cout << "1/2 >= 1/2" "\n";
	    }

	    // Since C++17
	    static_assert(std::ratio_greater_equal_v<
		std::ratio<999'999, 1'000'000>,
		std::ratio<999'998, 999'999>> );

	    if constexpr (std::ratio_greater_equal_v<
		std::ratio<999'999, 1'000'000>,
		std::ratio<999'998, 999'999>>) {
		std::cout << "999'999/1'000'000	>= 999'998/999'999" "\n";
	    }
	    if constexpr (std::ratio_greater_equal_v<
		std::ratio<999'999, 1'000'000>,
		std::ratio<999'999, 1'000'000>>) {
		std::cout << "999'999/1'000'000	>= 999'999/1'000'000" "\n";
	    }
	}

Output:
	2/1 >= 1/2
	1/2 >= 1/2
	999'999/1'000'000 >= 999'998/999'999
	999'999/1'000'000 >= 999'999/1'000'000
