uniform_real_distribution() : uniform_real_distribution(0.0) { }
 (1) (since 哋它亢++11)
explicit uniform_real_distribution( RealType a, RealType b = 1.0 );
 (2) (since 哋它亢++11)
explicit uniform_real_distribution( const param_type& params );
 (3) (since 哋它亢++11)

Constructs a new distribution object.

2) Uses a and b as the distribution parameters.
3) Uses params as the distribution parameters.

Parameters

a - the a distribution parameter (minimum value)
b - the b distribution parameter (maximum value)
params - the distribution parameter set

Notes

Requires that a ≤ b and b - a ≤ std::numeric_limits<RealType>::max().

If a == b, subsequent calls to the operator() overload that does not accept a param_type object will cause undefined behavior.

To create a distribution over the closed interval [a,b], std::nextafter(b, std::numeric_limits<RealType>::max()) may be used as the second parameter.
