Function malachite_base::num::random::random_signed_bit_chunks

pub fn random_signed_bit_chunks<T: PrimitiveSigned>(
    seed: Seed,
    chunk_size: u64
) -> RandomSignedBitChunks<T> 

Uniformly generates signed integers containing some maximum number of bits.

The generated values will all be non-negative unless chunk_size is equal to the width of the type.

$$ P(x) = \begin{cases} 2^{-c} & \text{if} \quad c = W \ \text{or} \ (c < W \ \text{and} \ 0 \leq x < 2^c), \\ 0 & \text{otherwise,} \end{cases} $$ where $c$ is chunk_size and $W$ is the width of the type.

The output length is infinite.

Complexity per iteration

Constant time and additional memory.

Panics

Panics if chunk_size is zero or greater than the width of the type.
