Expand description

Uniformly generates random natural (non-negative) signed integers.

$$ P(x) = \begin{cases} 2^{1-W} & \text{if} \quad x \geq 0, \\ 0 & \text{otherwise}, \end{cases} $$ where $W$ is the width of the type.

The output length is infinite.

Complexity per iteration

Constant time and additional memory.
