uniform_real::uniform_real

Constructs the distribution.

explicit uniform_real(result_type min0 = result_type(0), result_type max0 = result_type(1));

min0

The lower bound for random values.

max0

The upper bound for random values.

Precondition: min0 < max0

The constructor constructs an object whose stored value stored_min holds the value min0 and whose stored value stored_max holds the value max0.
