Example 1: c++ random float

float get_random()
{
    static std::default_random_engine e;
    static std::uniform_real_distribution<> dis(0, 1); // rage 0 - 1
    return dis(e);
}

Example 2: random number generator for floats

float r3 = LO + static_cast  (rand()) /( static_cast  (RAND_MAX/(HI-LO)));
