class template
<ratio>
std::ratio_greater_equal
template <class R1, class R2> ratio_greater_equal;
Compare ratios for equality or greater-than inequality
This type inherits from the appropriate integral_constant type (either true_type or false_type) to signal whether R1 compares greater than or equal to R2
The resulting type is the same as if ratio_greater_equal was defined as:
1
2
|
template <class R1, class R2>
struct ratio_greater_equal : integral_constant < bool, !ratio_less<R1,R2>::value > {};
|
Template parameters
- R1,R2
- ratio types to be compared.
Member constants
Inherited from integral_constant:
| member constant | definition |
|---|
| value | either true or false |
