Detailed Description

template<typename _RealType = double> class std::uniform_real< _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).

Constructor & Destructor Documentation

template<typename _RealType = double> std::uniform_real< _RealType >::uniform_real (_RealType __min = _RealType(0), _RealType __max = _RealType(1)) [inline, explicit]

Constructs a uniform_real object.

Parameters:

__min [IN] The lower bound of the distribution.
__max [IN] The upper bound of the distribution.

template<typename _RealType = double> template<typename _RealType1 , typename _CharT , typename _Traits > std::basic_ostream<_CharT, _Traits>& operator<< (std::basic_ostream< _CharT, _Traits > & __os, const uniform_real< _RealType1 > & __x) [friend]

Inserts a uniform_real random number distribution __x into the output stream __os.

Parameters:

__os An output stream.
__x A uniform_real random number distribution.

Returns:

The output stream with the state of __x inserted or in an error state.

template<typename _RealType = double> template<typename _RealType1 , typename _CharT , typename _Traits > std::basic_istream<_CharT, _Traits>& operator>> (std::basic_istream< _CharT, _Traits > & __is, uniform_real< _RealType1 > & __x) [friend]

Extracts a uniform_real random number distribution __x from the input stream __is.

Parameters:

__is An input stream.
__x A uniform_real random number generator engine.

Returns:

The input stream with __x extracted or in an error state.
