std::ratio_less_equal

Defined in header <ratio>
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.

Helper variable template

template< class R1, class R2 >
inline constexpr bool ratio_less_equal_v = ratio_less_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)
