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.

Contents

Helper variable template

template< class R1, class R2 >
inline constexpr bool ratio_less_equal_v = ratio_less_equal<R1, R2>::value;
 (since C++17)
[edit]

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)

Member types

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