Detailed Description

template<typename _RealType = double>
class std::uniform_real_distribution< _RealType >

Uniform continuous distribution for random numbers.

A continuous random distribution on the range [min, max) with equal probability throughout the range. The URNG should be real-valued and deliver number in the range [0, 1).

Member Typedef Documentation

◆ result_type

template<typename _RealType = double>
typedef _RealType std::uniform_real_distribution< _RealType >::result_type

The type of the range of the distribution.

Constructor & Destructor Documentation

◆ uniform_real_distribution() [1/2]

template<typename _RealType = double>
std::uniform_real_distribution< _RealType >::uniform_real_distribution ( )
inline

Constructs a uniform_real_distribution object.

The lower bound is set to 0.0 and the upper bound to 1.0

Definition at line 1784 of file random.h.

◆ uniform_real_distribution() [2/2]

template<typename _RealType = double>
std::uniform_real_distribution< _RealType >::uniform_real_distribution ( _RealType  __a,
_RealType  __b = _RealType(1) 
)
inlineexplicit

Constructs a uniform_real_distribution object.

Parameters
__a[IN] The lower bound of the distribution.
__b[IN] The upper bound of the distribution.

Definition at line 1793 of file random.h.

◆ min()

template<typename _RealType = double>
result_type std::uniform_real_distribution< _RealType >::min ( ) const
inline

Returns the inclusive lower bound of the distribution range.

Definition at line 1837 of file random.h.

◆ operator()()

template<typename _RealType = double>
template<typename _UniformRandomNumberGenerator >
result_type std::uniform_real_distribution< _RealType >::operator() ( _UniformRandomNumberGenerator &  __urng)
inline

◆ param() [1/2]

template<typename _RealType = double>
param_type std::uniform_real_distribution< _RealType >::param ( ) const
inline

Returns the parameter set of the distribution.

◆ param() [2/2]

template<typename _RealType = double>
void std::uniform_real_distribution< _RealType >::param ( const param_type &  __param)
inline

Sets the parameter set of the distribution.

Parameters
__paramThe new parameter set of the distribution.

Definition at line 1830 of file random.h.

◆ reset()

template<typename _RealType = double>
void std::uniform_real_distribution< _RealType >::reset ( )
inline

Resets the distribution state.

Does nothing for the uniform real distribution.
