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.
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
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) |

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>>);
}
