## Detailed Description

template<typename _RealType = double>
class std::uniform_real_distribution< _RealType >

Uniform continuous distribution for random numbers.

A continuous random distribution on the range [min, max) with equal probability throughout the range. The URNG should be real-valued and deliver number in the range [0, 1).

Since
  C++11
