Description

`param_type` public construct/copy/destruct

<
```
explicitparam_type(RealTypea=1.0,RealTypeb=1.0);
```
>
Построение a<param_type>из параметров «a» и «b» распределения.
Требуется: a >0 & & b >0

`param_type` public member functions

<
```
RealTypea()const;
```
>
Возвращает параметр «а» дистрибуции.
<
```
RealTypeb()const;
```
>
Возвращает параметр «b» распределения.

`param_type` friend functions

template<typenameCharT,typenameTraits>
 friendstd::basic_ostream<CharT,Traits>&
 operator<<(std::basic_ostream<CharT,Traits>&os,
            constparam_type&param);

Пишет<param_type><std::ostream>.

template<typenameCharT,typenameTraits>
 friendstd::basic_istream<CharT,Traits>&
 operator>>(std::basic_istream<CharT,Traits>&is,
            constparam_type&param);

Читает<param_type>из<std::istream>

<
```
friendbooloperator==(constparam_type&lhs,constparam_type&rhs);
```
>
Возвращается истинно, если два набора параметров одинаковы.
<
```
friendbooloperator!=(constparam_type&lhs,constparam_type&rhs);
```
>
Возвращается истинно, если два набора параметров различны.
