Description
method
const MKL_INT
Generation method; the specific value is
VSL_RNG_METHOD_UNIFORMBITS64_STD
stream
VSLStreamStatePtr
Pointer to the stream state structure
n
const MKL_INT
Number of random values to be generated
Output Parameters
Name
Type
Description
r
unsigned MKL_INT64*
Vector of
n
64-bit random integer numbers with uniform bit distribution.
Description
The
vRngUniformBits64
function generates uniformly distributed bits in 64-bit chunks. Unlike
vRngUniformBits
, which provides the output of underlying integer recurrence and does not guarantee uniform distribution across bits,
vRngUniformBits64
is designed to ensure each bit in the 64-bit chunk is uniformly distributed. See VS Notes for details.
