< cpp‎ | numeric‎ | random‎ | uniform real distribution

explicit uniform_real_distribution( RealType a = 0.0, RealType b = 1.0 ); | (1) | (since C++11)
explicit uniform_real_distribution( const param_type& params ); | (2) | (since C++11)

Constructs new distribution object. The first version uses `a` and `b` as the distribution parameters, the second version 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.
