normal_distribution() : normal_distribution(0.0) {}
(1) (since C++11)
explicit normal_distribution( RealType mean, RealType stddev = 1.0 );
(2) (since C++11)
explicit normal_distribution( const param_type& params );
(3) (since C++11)

Constructs a new distribution object. (2) uses mean and stddev as the distribution parameters. (3) uses params as the distribution parameters.

The behavior is undefined if stddev is not greater than zero.

[edit] Parameters

mean - the μ distribution parameter (mean)
stddev - the σ distribution parameter (standard deviation)
params - the distribution parameter set

[edit] Defect reports

The following behavior-changing defect reports were applied retroactively to previously published C++ standards.
