__construct

__construct(array|int $seed)

(→ init_by_array), exactly as numpy.random.RandomState accepts.

nextUint32

nextUint32(): int

The next tempered 32-bit word (numpy next_uint32 / genrand_uint32).

nextDouble

nextDouble(): float

A single double in [0, 1) (numpy legacy next_double / random_sample).

randomSample

randomSample(int $n): array

nextGauss

nextGauss(): float

A single standard normal (numpy legacy gauss: Box–Muller polar).

standardNormal

standardNormal(int $n): array

randomInterval

randomInterval(int $max): int

A uniform integer in [0, $max] by numpy's smallest-mask rejection (rk_interval). Uses a 32-bit draw when the range fits in 32 bits, else a 64-bit draw — matching numpy's legacy buffered path.

randint

randint(int $low, int $high, int $size): array

permutation

permutation(int $n): array

shuffle

shuffle(array $arr): void

In-place legacy Fisher–Yates shuffle (numpy RandomState.shuffle).
