integer(kind(hiprand_status_success)) function | hiprandgenerateuniformdouble_ (generator, output_data, n) |
Detailed Description
Generates uniformly distributed double-precision floating-point values.
Generates n
uniformly distributed 64-bit double-precision floating-point values and saves them to output_data
.
Generated numbers are between 0.0
and 1.0
, excluding 0.0
and including 1.0
.
- Parameters
-
generator - Generator to use output_data - Pointer to memory to store generated numbers n - Number of floats to generate
Note: When generator
is of type: HIPRAND_RNG_PSEUDO_MRG32K3A
, HIPRAND_RNG_PSEUDO_MTGP32
, or HIPRAND_RNG_QUASI_SOBOL32
, then the returned double
values are generated from only 32 random bits each (one unsigned int
value per one generated double
).
- Returns
- HIPRAND_STATUS_NOT_INITIALIZED if the generator was not initialized
- HIPRAND_STATUS_LAUNCH_FAILURE if generator failed to launch kernel
- HIPRAND_STATUS_LENGTH_NOT_MULTIPLE if
n
is not a multiple of the dimension of used quasi-random generator
- HIPRAND_STATUS_SUCCESS if random numbers were successfully generated
- HIPRAND_STATUS_NOT_INITIALIZED if the generator was not initialized
