Overview

A symmetric probability distribution whereby a finite number of values are equally likely to be observed: every one of n values has equal probability 1/n.

Defined in:

Constructors

• .new(min : Int64, max : Int64)

  Create a new discrete uniform object with parameters min and man

Class Method Summary

• .sample(min : Int, max : Int, rng : Random | Nil = nil)

  Returns a random integer from min to max

• .sample(n : Int, min : Int, max : Int, rng : Random | Nil = nil)

  Returns an array of random integers from min to max

Instance Method Summary

• #sample(rng : Random | Nil = nil) : Int

  Returns a random integer from min to max
