public choice(a: Array, i: number, j: number): any: * source

import choice from '@randomized/random/src/api/choice.js'

Sample a single element from an array.

Return:

any	The sampled element.

public randfloat(i: number, j: number): number: * source

import randfloat from '@randomized/random/src/api/randfloat.js'

Returns a double in interval [i, j[ (i included, j excluded) according to a uniform distribution.

Return:

number

A double in the interval [i, j[ taken uniformly at random.

public randint(i: number, j: number): number: * source

import randint from '@randomized/random/src/api/randint.js'

Returns an integer in interval [i, j[ (i included, j excluded) according to a uniform distribution.

Return:

number

An integer in the interval [i, j[ taken uniformly at random.

public randrange(start: number, stop: number, step: number): number: * source

import randrange from '@randomized/random/src/api/randrange.js'

Pick an element from range(start, stop, step) uniformly at random.

Return an element from range(start, stop, step) selected uniformly at random. If step is positive, this set corresponds to {x: x in [start, stop[ AND x % step = 0}. If step is negative, the range has to be given in reverse order, that is, largest value first, smallest value second. Both the starting value and the step value are optional. By default the starting value is 0. The default for the step value is 1.

TODO: Handle empty ranges.

Return:

number

The picked element.

public reservoir(k: number, iterable: Iterable, output: Array): Array: * source

import reservoir from '@randomized/random/src/api/reservoir.js'

Reservoir sampling.

Return:

Array

The output array.

public sample(n: number, a: Array, i: number, j: number): * source

import sample from '@randomized/random/src/api/sample.js'

Take a sample of size n (without replacement) from the items i through j-1 of the input array. This is done in-place. The sample can be retrieved from position i to i+n.

public shuffle(a: Array, i: number, j: number): * source

import shuffle from '@randomized/random/src/api/shuffle.js'

Shuffle array in-place between positions i and j-1 (inclusive). The other positions are left untouched.

public shuffled(iterable: Iterable): Array: * source

import shuffled from '@randomized/random/src/api/shuffled.js'

Given an input iterable, constructs an array containing the elements of the input shuffled uniformly at random.

Return:

Array

The constructed array.
