INTEGER, INTENT(IN) |
Generation method; the specific value is VSL_RNG_METHOD_UNIFORMBITS32_STD |
stream |
TYPE (VSL_STREAM_STATE), INTENT(IN) |
Descriptor of the stream state structure. |

r |
INTEGER (KIND=4), INTENT(OUT) |
Vector of n 32-bit random integer numbers with uniform bit distribution. |
Description
The vRngUniformBits32 function generates uniformly distributed bits in 32-bit chunks. Unlike vRngUniformBits, which provides the output of underlying integer recurrence and does not guarantee uniform distribution across bits, vRngUniformBits32 is designed to ensure each bit in the 32-bit chunk is uniformly distributed. See VS Notes for details.
