RealType m() const;	(1)	(since C++11)
RealType s() const;	(2)	(since C++11)

Returns the parameters the distribution was constructed with.

1) Returns the mean m distribution parameter. It defines the location of the peak. The default value is 0.0.

2) Returns the deviation s distribution parameter. The default value is 1.0.

Parameters

(none)

Return value

1) The mean m distribution parameter.

2) The deviation s distribution parameter.
