Methods

bottom(int n) → List<T>

Available on Iterable<T>, provided by the IterableNumX extension

Returns the n smallest elements in ascending order.
clampAll(T lo, T hi) → Iterable<T>

Available on Iterable<T>, provided by the IterableNumX extension

Clamps every element to [lo, hi].
normalize() → List<double>

Available on Iterable<T>, provided by the IterableNumX extension

Normalizes elements to 0, 1 based on min/max scaling. Returns an empty list if empty or if min == max.
product({T? identity}) → T

Available on Iterable<T>, provided by the IterableNumX extension

Product of all elements. Returns identity (default 1) if empty.
runningProduct() → Iterable<T>

Available on Iterable<T>, provided by the IterableNumX extension

Cumulative product as a lazy iterable.
runningSum() → Iterable<T>

Available on Iterable<T>, provided by the IterableNumX extension

Running (prefix) sum as a lazy iterable.
sum({T? identity}) → T

Available on Iterable<T>, provided by the IterableNumX extension

Sum of all elements. Returns identity (default 0) if empty.
top(int n) → List<T>

Available on Iterable<T>, provided by the IterableNumX extension

Returns the n largest elements in descending order.
