NAME¶

std::uniform_real_distribution::uniform_real_distribution - std::uniform_real_distribution::uniform_real_distribution

Synopsis¶

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.
