explicit uniform_real_distribution( const param_type& params ); | (3) | (since C++11) |
Constructs a new distribution object.
a and b as the distribution parameters.params as the distribution parameters.| a | - | the a distribution parameter (minimum value) |
| b | - | the b distribution parameter (maximum value) |
| params | - | the distribution parameter set |
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.
The following behavior-changing defect reports were applied retroactively to previously published C++ standards.
