randomgen.rdrand.RDRAND.random_raw¶

RDRAND.random_raw(size=None, output=True)¶

Return randoms as generated by the underlying BitGenerator

Parameters:¶

size=None¶

Output shape. If the given shape is, e.g., (m, n, k), then m * n * k samples are drawn. Default is None, in which case a single value is returned.

output=True¶

Output values. Used for performance testing since the generated values are not returned.

Returns:¶

out – Drawn samples.

Return type:¶

{uint64, ndarray, None}

Raises:¶

RuntimeError – Raised if the RDRAND instruction fails after retries.
