template< class R1, class R2 > struct ratio_less_equal : std::integral_constant; | (since C++11) |
If the ratio R1 is less than or equal to the ratio R2, provides the member constant value equal true. Otherwise, value is false.
template< class R1, class R2 > inline constexpr bool ratio_less_equal_v = ratio_less_equal<R1, R2>::value; | (since C++17) |
| value
[static] | true if R1::num * R2::den <= R2::num * R1::den, or equivalent expression that avoids overflow , false otherwise (public static member constant) |
| operator bool | converts the object to bool, returns value (public member function) |
| operator()
(C++14) | returns value (public member function) |
