Public Member Functions
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
