This method corresponds to the system's drand48() function. It generates pseudo-random number using a linear congruential algorithm and 48-bit integer arithmetic. This method returns decimal values uniformly distributed over the interval [0.0 , 1.0].
Consult your operating system's documentation for the exact behavior of this method.
