Returns the distribution parameters the distribution has been constructed with.

1) Returns the α distribution parameter. It is also known as the shape parameter. The default value is 1.0.
2) Returns the β distribution parameter. It is also known as the scale parameter. The default value is 1.0.

[edit] Parameters

(none)

[edit] Return value

1) Floating point value identifying the α parameter
2) Floating point value identifying the β parameter
