A uniform_real_distribution random number distribution produces random numbers x, a ≤ x < b , distributed according to the constant probability density function p(x | a,b) = 1 / (b - a) . [ Note: This implies that p(x | a,b) is undefined when a == b. — end note ]

explicit uniform_real_distribution(RealType a = 0.0, RealType b = 1.0);
Requires: a ≤ b and b - a ≤ numeric_limits<RealType>::max() .
Effects: Constructs a uniform_real_distribution object; a and b correspond to the respective parameters of the distribution.
Returns: The value of the a parameter with which the object was constructed.
Returns: The value of the b parameter with which the object was constructed.
