MMrng Module is written with, and requires, REALbasic, and generates pseudo-random doubles (>= 0 and <1). This generator uses the method of Mitchell and Moore as described in "The Art of Computer Programming", Vol. 2, 2nd edition, p. 26, by Donald E. Knuth (Addison-Wesley). The advantage of this method is its long period (greater than 3.6 x 10^16) and that no multiplication or division is required.
