ratio_greater_equal
(C++11)
Defined in header
<ratio>
template< class R1, class R2 >
struct ratio_greater_equal : std::integral_constant <bool, /* see below */> { };
(since C++11)
struct ratio_greater_equal : std::integral_constant <bool, /* see below */> { };
If the ratio R1 is greater than or equal to the ratio R2, provides the member constant value equal true. Otherwise, value is false.
