Detailed Description
template<class T, class Compare = std::less<T>>
class ripple::test::csf::Histogram< T, Compare >
Basic histogram.
Histogram for a type T that satisfies
- Default construction: T{}
- Comparison : T a, b; bool res = a < b
- Addition: T a, b; T c = a + b;
- Multiplication : T a, std::size_t b; T c = a * b;
- Divison: T a; std::size_t b; T c = a/b;

◆ percentile()
template<class T , class Compare = std::less<T>>
| T ripple::test::csf::Histogram< T, Compare >::percentile | ( | float | p | ) | const |
Calculate the given percentile of the distribution.
- Parameters
-
p Percentile between 0 and 1, e.g. 0.50 is 50-th percentile If the percentile falls between two bins, uses the nearest bin.
- Returns
- The given percentile of the distribution
