Detailed Description

template<class RealType = float>
class rocrand_cpp::uniform_real_distribution< RealType >

Produces random floating-point values uniformly distributed on the interval (0, 1].

Template Parameters

RealType

- type of generated values. Only float, double and half types are supported.

Member Function Documentation

◆ operator()()

template<class RealType = float>

template<class Generator >

void rocrand_cpp::uniform_real_distribution< RealType >::operator() ( Generator &  g, RealType *  output, size_t  size  )

inline

Fills output with uniformly distributed random floating-point values.

Generates size random floating-point values uniformly distributed on the interval (0, 1], and stores them into the device memory referenced by output pointer.

Parameters

g	- An uniform random number generator object
output	- Pointer to device memory to store results
size	- Number of values to generate

Requirements:

• The device memory pointed by output must have been previously allocated and be large enough to store at least size values of RealType type.
• If generator g is a quasi-random number generator (rocrand_cpp::sobol32_engine), then size must be a multiple of that generator's dimension.
