Function malachite_nz::integer::random::uniform_random_integer_range

pub fn uniform_random_integer_range(
    seed: Seed,
    a: Integer,
    b: Integer
) -> UniformRandomIntegerRange 

Uniformly generates random Integers in the half-open interval $[a, b)$.

$a$ must be less than $b$.

$$ P(x) = \begin{cases} \frac{1}{b-a} & \text{if} \quad a \leq x < b, \\ 0 & \text{otherwise}. \end{cases} $$

The output length is infinite.

Expected complexity per iteration

$T(n) = O(n)$

$M(n) = O(n)$

where $T$ is time, $M$ is additional memory, and $n$ is b.significant_bits().

Panics

Panics if $a \geq b$.
