Original sentence: This algorithm assumes that one has access to the inverse of the cumulative distribution (easy to calculate with a discrete distribution, can be approximated for continuous distributions) and a computational primitive called "random()" which returns a arbitrary-precision floating-point-value in the range of [0,1)
