Description

`param_type` public construct/copy/destruct

```
( alpha = ,  beta = );
```
Constructs a param_type from the "alpha" and "beta" parameters of the distribution.

Requires: alpha > 0, beta > 0

`param_type` public member functions

```
 () ;
```
Returns the "alpha" parameter of the distribtuion.
```
 () ;
```
Returns the "beta" parameter of the distribution.

`param_type` friend functions

template<typename CharT, typename Traits> 
   
  ( os, 
             param_type & param);

Writes a param_type to a std::ostream.

template<typename CharT, typename Traits> 
   
  ( is, 
             param_type & param);

Reads a param_type from a std::istream.

```
 (param_type & lhs, param_type & rhs);
```
Returns true if the two sets of parameters are the same.
```
 (param_type & lhs, param_type & rhs);
```
Returns true if the two sets of parameters are the different.
