# randomgen.mt64.MT64.random_raw¶

- MT64.random_raw(
*size=None*,*output=True*)¶ Return randoms as generated by the underlying BitGenerator

- Parameters
**size**int or tuple of ints, optionalOutput 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**bool, optionalOutput values. Used for performance testing since the generated values are not returned.

- Returns
**out**{uint64, ndarray, None}Drawn samples.

Notes

This method directly exposes the the raw underlying pseudo-random number generator. All values are returned as unsigned 64-bit values irrespective of the number of bits produced by the PRNG.

See the class docstring for the number of bits returned.
