26.5.8.2.2 Class template uniform_real_distribution[rand.dist.uni.real]

A uniform_real_distribution random number distribution produces random numbers x, ax < b , distributed according to the constant probability density function p(x | a,b) = 1 / (b - a) .

```template<class RealType = double>
class uniform_real_distribution{
public:
// types
typedef RealType result_type;
typedef unspecified param_type;

// constructors and reset functions
explicit uniform_real_distribution(RealType a = 0.0, RealType b = 1.0);
explicit uniform_real_distribution(const param_type& parm);
void reset();

// generating functions
template<class URNG>
result_type operator()(URNG& g);
template<class URNG>
result_type operator()(URNG& g, const param_type& parm);

// property functions
result_type a() const;
result_type b() const;
param_type param() const;
void param(const param_type& parm);
result_type min() const;
result_type max() const;
};
```

``` explicit uniform_real_distribution(RealType a = 0.0, RealType b = 1.0); ```

Requires: ab and b - anumeric_limits<RealType>::max() .

Effects: Constructs a uniform_real_distribution object; a and b correspond to the respective parameters of the distribution.

``` result_type a() const; ```

Returns: The value of the a parameter with which the object was constructed.

``` result_type b() const; ```

Returns: The value of the b parameter with which the object was constructed.
