Defined in header <ratio> | ||
---|---|---|
template< class R1, class R2 > struct ratio_greater_equal : std::integral_constant; |
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) |
Member types

value_type | bool |
