pub struct Lowest { /* private fields */ }
Expand description
Returns lowest value over the last length
values for timeseries of type ValueType
§Parameters
Has a single parameter length
: PeriodType
length
should be > 0
§Input type
Input type is ValueType
§Output type
Output type is ValueType
§Examples
use yata::core::Method;
use yata::methods::Lowest;
let values = [1.0, 2.0, 3.0, 2.0, 1.0, 0.5, 2.0, 3.0];
let r = [1.0, 1.0, 1.0, 2.0, 1.0, 0.5, 0.5, 0.5];
let mut lowest = Lowest::new(3, &values[0]).unwrap();
(0..values.len()).for_each(|i| {
let v = lowest.next(&values[i]);
assert_eq!(v, r[i]);
});
§Performance
O(length
)
This method is relatively slow compare to the other methods.
