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